Abstract The structural, magnetic and magnetocaloric properties of 50% Mn substituted ErFeO3 are studied by X-ray diffraction, magnetization and specific heat measurements. ErFe0.5Mn0.5O3 crystallizes in an orthorhombic structure (Pbnm). DC magnetization and specific heat studies point to two magnetic transitions: (i) Fe3+/Mn3+ ordering, TN ~ 245 K and (ii) spin re-orientation transition, TSR ~ 218 K. Below TSR, ErFe0.5Mn0.5O3 exhibits a reduction in magnetization and coercivity which could be due to a Γ4-Γ1 magnetic transition. Interestingly, we have observed a negative magnetization in field cooled curves at lower temperatures under lower applied fields (
