Abstract

Erbium orthochromite, ErCrO3, is a distorted-perovskite which has antiferromagnetic ground state below 10 K while Cr3+ magnetic moments order at 133 K. The temperature dependence of magnetization is studied across different magnetic phases for ErCrO3 and different magnetization isotherms are analyzed. In the presence of external magnetic field, polycrystalline ErCrO3 develops weak ferromagnetism from antiferromagnetic ground state. These magnetic phase transitions are observed to be of first order which is justified by thermal hysteresis and Arrott-plots.
