Abstract
Temperature dependent magnetic properties of Pr1−x Gd x MnO3 (x = 0.3, 0.5, 0.7) have been reported. All the samples belong to the family of orthorhombic perovskites structure with Pbnm space group. Below the Neel temperature T N (~92 K), a magnetization reversal is observed in DC magnetization measurements (at 50 Oe), in all the samples. This may be due to the competition between two magnetic sublattices (Pr + Gd and Mn) coupled with a negative exchange interaction. In the temperature dependent magnetization data, the bifurcation between the zero field cooled and field cooled magnetization is attributed to the canted antiferromagnetism. Ferrimagnetic characteristic is observed in the field dependent magnetization curve below T N .
