Education

Chilton completed his Advanced Bachelor of Science (Honors) degree at Monash University in 2011 where he finished his final year project with Stuart R. Batten and Keith S. Murray. [3] His research at Monash included the synthesis and characterization of low-symmetry dysprosium complexes, [5] [6] and mixed-metallic lanthanide-transition metal clusters, [7] that display single molecule magnetism. During this time, he also designed a software program, PHI, for the calculation of the magnetic properties of paramagnetic coordination complexes. [8] Chilton completed his Ph.D. on magnetochemistry at the University of Manchester, supervised by Richard Winpenny and Eric McInnes in 2015. [9]

Research and career

Chilton completed postdoctoral research at the Engineering and Physical Sciences Research Council National EPR facility in collaboration with the University of Manchester. In 2016, he was awarded the British Ramsay Memorial Fellowship (2016–2018) to research how coordination chemistry can be used to engineer specific magnetic states of lanthanide ions. From 2017, He began work as a Senior Lecturer and a Royal Society University Research Fellow in the Department of Chemistry at the University of Manchester. [3] [10] In 2021, he was promoted to Professor in Computational and theoretical chemistry, and in 2023 he moved to The Australian National University and holds a joint appointment with The University of Manchester.

Chilton's research is in the areas of computational chemistry and magnetochemistry, specifically on the design of high-temperature single molecule magnets, molecular spin qubits for quantum information science, understanding paramagnetic MRI contrast agents, unravelling the electronic structure of uranium coordination complexes, magnetic interactions between f-elements, and in developing computational methods and tools. [3] [1] [11]

Notable work

In 2017, with synthetic chemist David P. Mills, Chilton led the magnetic characterization of a dysprosocenium ion single-molecule magnet, which exhibits magnetic hysteresis at 60 Kelvin. [12]

Chilton has also collaborated in developing software to be used in chemical research, particularly in modelling magnetic relaxation and magnetic properties of coordination complexes. [13] In 2013, with Alessandro Soncini he designed a computer program for the determination of the orientation of the magnetic anisotropy of the mJ = ±15/2 state of DyIII via electrostatic optimization of the aspherical electron density distribution. [14] He also designed a program named PHI for the calculation of the magnetic properties of paramagnetic coordination complexes in the same year. [8] In 2019, with his post-doctoral researcher Daniel Reta, designed CC-FIT2 , a tool for the fitting of experimental AC magnetic susceptibility data using the (generalized) Debye model, extraction of magnetic relaxation times with associated uncertainties, and fitting the temperature dependence of these data accounting for uncertainties in the underlying relaxation times.

<span class="mw-page-title-main">Dysprosium</span> Chemical element with atomic number 66 (Dy)

Dysprosium is a chemical element; it has symbol Dy and atomic number 66. It is a rare-earth element in the lanthanide series with a metallic silver luster. Dysprosium is never found in nature as a free element, though, like other lanthanides, it is found in various minerals, such as xenotime. Naturally occurring dysprosium is composed of seven isotopes, the most abundant of which is 164Dy.

<span class="mw-page-title-main">Ferromagnetism</span> Mechanism by which materials form into and are attracted to magnets

Ferromagnetism is a property of certain materials that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a magnet, which is a consequence of their substantial magnetic permeability.

<span class="mw-page-title-main">Holmium</span> Chemical element with atomic number 67 (Ho)

Holmium is a chemical element; it has symbol Ho and atomic number 67. It is a rare-earth element and the eleventh member of the lanthanide series. It is a relatively soft, silvery, fairly corrosion-resistant and malleable metal. Like many other lanthanides, holmium is too reactive to be found in native form, as pure holmium slowly forms a yellowish oxide coating when exposed to air. When isolated, holmium is relatively stable in dry air at room temperature. However, it reacts with water and corrodes readily, and also burns in air when heated.

The lanthanide or lanthanoid series of chemical elements comprises at least the 14 metallic chemical elements with atomic numbers 57–70, from lanthanum through ytterbium. In the periodic table, they fill the 4f orbitals. Lutetium is also sometimes considered a lanthanide, despite being a d-block element and a transition metal.

<span class="mw-page-title-main">Nuclear magnetic resonance spectroscopy</span> Laboratory technique

Nuclear magnetic resonance spectroscopy, most commonly known as NMR spectroscopy or magnetic resonance spectroscopy (MRS), is a spectroscopic technique based on re-orientation of atomic nuclei with non-zero nuclear spins in an external magnetic field. This re-orientation occurs with absorption of electromagnetic radiation in the radio frequency region from roughly 4 to 900 MHz, which depends on the isotopic nature of the nucleus and increased proportionally to the strength of the external magnetic field. Notably, the resonance frequency of each NMR-active nucleus depends on its chemical environment. As a result, NMR spectra provide information about individual functional groups present in the sample, as well as about connections between nearby nuclei in the same molecule. As the NMR spectra are unique or highly characteristic to individual compounds and functional groups, NMR spectroscopy is one of the most important methods to identify molecular structures, particularly of organic compounds.

A single-molecule magnet (SMM) is a metal-organic compound that has superparamagnetic behavior below a certain blocking temperature at the molecular scale. In this temperature range, an SMM exhibits magnetic hysteresis of purely molecular origin. In contrast to conventional bulk magnets and molecule-based magnets, collective long-range magnetic ordering of magnetic moments is not necessary.

In magnetism, a nanomagnet is a nanoscopic scale system that presents spontaneous magnetic order (magnetization) at zero applied magnetic field (remanence).

Magnetochemistry is concerned with the magnetic properties of chemical compounds and elements. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin–orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin–orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.

<span class="mw-page-title-main">Paramagnetic nuclear magnetic resonance spectroscopy</span> Spectroscopy of paramagnetic compounds via NMR

Paramagnetic nuclear magnetic resonance spectroscopy refers to nuclear magnetic resonance (NMR) spectroscopy of paramagnetic compounds. Although most NMR measurements are conducted on diamagnetic compounds, paramagnetic samples are also amenable to analysis and give rise to special effects indicated by a wide chemical shift range and broadened signals. Paramagnetism diminishes the resolution of an NMR spectrum to the extent that coupling is rarely resolved. Nonetheless spectra of paramagnetic compounds provide insight into the bonding and structure of the sample. For example, the broadening of signals is compensated in part by the wide chemical shift range (often 200 ppm in 1H NMR). Since paramagnetism leads to shorter relaxation times (T1), the rate of spectral acquisition can be high.
