Hematine

Last updated September 09, 2025

Hematine (also magnetic hematite, hemalyke or hemalike) is an artificial magnetic material.^[1] Hematine is widely used in jewelry.^{[ citation needed ]}

Although it is claimed by many that it is made from ground hematite or iron oxide mixed with a resin, analysis (of one object) has demonstrated it to be an entirely artificial compound, a barium-strontium ferrite ((Ba,Sr)Fe12O19).^[2]
