R-plane hematite. a, Crystallographic structure of hematite, α-Fe2O3. The single crystal that we use has an R-plane termination making a 33° angle with the easy axis [001] of α-Fe2O3. Above the spin-flop, the (111) plane becomes an easy plane. b, Temperature dependency of the magnetization in the single crystal of hematite measured by SQUID. The weak ferromagnetic moment is suppressed below the Morin temperature of 260 K (Inset) At 200 K, below the Morin temperature, we note the complete absence of ferromagnetic moment.
