Field-enhanced magnetic moment in ellipsoidal nano-hematite

Field-enhanced magnetic moment in ellipsoidal nano-hematite

Bulk hematite is a canted antiferromagnet at room temperature and displays weak magnetic coercivity above the Morin transition temperature T _M  ∼ 262 K. Below T _M , hematite displays traditional antiferromagnetic behavior, with no net magnetic moment or magnetic hysteresis. Here, we report that el...
