Hysteresis profile of a ferrimagnet. The remanent magnetization M, saturation magnetization Msat, and coercive force Bcf are indicated. The typical parameters of the hysteresis plot for maghemite are M = 50 emu/cm3 (47), Msat = 377 emu/cm3 (48), and Bcf = 233 G (48). For magnetite, Msat = 480 emu/cm3 (47) and Bcf = 180–300 G (48).
