Magnetization Reversal in Fe Doped SmCrO3

AbstractThe compound SmCr1-xFexO3 perovskites were prepared by citric acid route. The samples were characterized by XRD and SEM The temperature and field dependent magnetization measurements were carried out in the temperature range of 5K to 400K at 0.01T field and -5T to 5 T field at 2K. SmCrO3 compound has shown two magnetic transition temperatures (TN1 and TN2) at 197K and 38K. The observed behavior at 197K is the characteristic of anti-ferromagnetic ordering of Cr 3+ moments with weak ferromagnetism. The drop in magnetization below 38K is due to the spin reorientation of Sm3+ in anti ferromagnetic arrangement and Cr3+spins. The doping of Fe in SmCrO3 compound has shown a decrease in TN1 and also the two magnetization reversals at 177K and 57K. The magnetic behavior at low temperatures is (T
