environmental can heamatite iron ore be magnetised

Apr 18 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
