Nov 21, 2021 Yes, hematite being an iron ore is magnetic in nature. It is antiferromagnetic in nature below the Morin transition ie; approximately at 250 K. And it acts as a weak ferromagnet above the Morin transition and Neel temperature, which is approximately 948 K. In addition to this, hematite above the Neel temperature is a pure paramagnet

Magnetite is a form of iron oxide, Fe 3 O 4, which possesses uniquely iron in both the Fe 2+ and Fe 3+ oxidation states. Bearing the form of an inverse spinel, it’s magnetic properties are highly valued. Addition of magnetite to soil is advantageous as it can later be removed easily by using magnets. It can occur naturally in soil, or be added as a soil treatment agent

Dec 19, 2017 The magnetic signature of hematite, in major hysteresis loops, FORC diagrams, and thermo-magnetic curves, can be easily muted when magnetite is ≥5 wt%. IRM demagnetization curves, however, were able to identify hematite when magnetite coexisted in higher concentrations, since hematite can maintain its contribution to remanence more than

Jan 31, 2018 Hematite has unpaired electrons that cause its magnetic properties. It is paramagnetic because it has only ferric ion (Fe 3+).The electron configuration of Fe 3+ is 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 where 5 unpaired electrons are present.
