Abstract
Structural, magnetic and magnetocaloric properties of La0.5□0.1Ca0.4MnO3 manganite prepared by conventional solid state reaction route have been carried out. The X-ray diffraction characterization has revealed that this sample crystallized in the orthorhombic symmetry, with Pnma space group. In order to check if this sample can be good candidate for magnetic refrigeration, relative cooling power was determined depicting that the sample can be useful for magnetic refrigeration at with about 232.20 J/kg under a magnetic field of 5 T. The magnetocaloric data has been well analyzed by using the Landau theory. The theoretical and experimental plots seem nearly similar. Based on these amazing properties, our compound is suggested as an effective candidate for various potential applications such as refrigeration application.
