Abstract :In present study, the effects of copper substitution on the magnetic and magnetocaloric properties of La0.7Sr0.3Mn1-xCuxO3 manganite samples were investigated. La0.7Sr0.3Mn1-xCuxO3 samples were obtained by using sol-gel method. X-ray diffraction analyses were performed to determine structural properties such as lattice parameters and crystal structure. The crystal structure of the samples is rhombohedral with space group
