Abstract
PrCrO3(PCO) samples were prepared by Citric acid route .The samples were characterized by XRD and SEM. The sample exhibits a single phase orthorhombic structure with Pbnm space group. The temperature dependent and field dependent magnetic measurements were measured in the range of 5K-400K at 100 Oe field and 0 to 5T field at 5K and RT respectively .The temperature dependence of dc magnetic properties show that the ZFC and FC magnetization curves are irreversible strongly and nearly symmetrical below 240K .There appears a novel magnetization behavior with negative magnetization characteristic in ZFC, the diamagnetism like behavior .This behavior exhibits the coexistence of canted anti-ferromagnetic and weak ferromagnetic phase and the existence of competition mechanism below 240K . This behavior can be interpreted from the interaction between Pr3+and Cr3+moments .The field and temperature dependent magnetization indicates the phase transition from canted anti ferromagnetic to paramagnetic occurred below 240K. In the region of higher temperature above 240K, PrCrO3behaved as a typical Curie-Weiss paramagnetic.Keywords: Orthochromites ,Multiferroics ,Neel temperature.PACS: 75.85 +t, 75.60 d, 75.50.Ee,75.30 Et,76.30 Kg
