Is Hematite Magnetic? - Techiescientist

1 天前  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.
