摘要
The magnetic properties of irradiated single crystal hematite are recovered by annealing. With increasing annealing temperature the amount of the weak ferromagnetic (WF) phase decreases at measurement temperature of 140 K, then the new low-temperature transition temperature decreases while the Morin temperature increases. The annealing at 163 to 178 degrees C leads to the disappearance of the WF phase at low temperatures. The Morin transition temperature reaches its nonirradiated value only after annealing at 455 degrees C. In the single crystal hematite irradiated with 29 MeV alpha-particles two stages of annealing are observed.
