Magnetic and magnetocaloric properties of 0.5La0.7Ca0.2Sr0.1MnO3/0.5La0.7Te0.3MnO3 composite

Abstract

In this work, the magnetic and magnetocaloric properties of 0.5La0.7Ca0.2Sr0.1MnO3/0.5La0.7Te0.3MnO3 composite have been investigated. The 0.5La0.7Ca0.2Sr0.1MnO3/0.5La0.7Te0.3MnO3 composite has been composed by mixing the La0.7Ca0.2Sr0.1MnO3 and La0.7Te0.3MnO3 manganites with a ratio of 0.5:0.5, synthesized by using the standard solid state method. In order to investigate the magnetic and magnetocaloric properties of the samples, magnetization measurements dependence on temperature and magnetic field have been performed by using physical property measurement system. The nature of the magnetic phase transition for all materials has been identified by using Banerjee criterion and Landau theory and according to both methods the magnetic phase transition is second order. Magnetic entropy change values have been calculated by using Maxwell relation and Landau theory. Based on Maxwell relation, the maximum magnetic entropy change value of the composite has been calculated as 3.70 Jkg-1K-1 for 5 T.
