We investigate the effect of Erbium doping on the structural, magnetic and magnetocaloric properties of Pr0.6-xErxSr0.4MnO3 (x = 0.0, 0.1 and 0.2) powder samples. Our polycrystalline samples were synthesized using the solid-state reaction at high temperature. X-ray diffraction characterizations showed that all our studied samples crystallize in the distorted orthorhombic system with Pnma space group. All our synthesized samples exhibit a paramagnetic-ferromagnetic transition with decreasing temperature. The magnetic transition temperature TC is found to decrease continuously with increasing Er concentration. It was found that the maximum value of the magnetic entropy change for Pr0.6-xErxSr0.4MnO3 sample reached 
in a magnetic applied filed of 2T.
