Magnetic Properties on Ferromagnetic FeAlO3

This paper investigates the magnetoelectric properties of the FeAlO₃ by the Mossbauer spectroscopy and vibrating sample magnetometer(VSM). The temperature dependence of magnetization curve was measured from 65 to 320 K ranges. The hysteresis curves for FeAlO₃ showed ferromagnetic phase. It is noticeable that magnetic hysteresis curve shows a pinched-like shape, which is related with a spin torque effect of nanoring materials. The saturation magnetization and coercive force were found to be 39.4 emu/g and 1,045 Oe at 65 K. The Curie temperature, T_C, is determined to be 250 K from temperature dependence of magnetization curve under the applied field of 100 Oe. It accords with the result of Mossbauer spectroscopy analysis, too.
