Abstract

In this work, the magnetic and magnetocaloric properties of0.5La0.7Ca0.2Sr0.1MnO3/0.5La0.7Te0.3MnO3 (0.5LCSM/0.5LTM) composite have beeninvestigated. The 0.5LCSM/0.5LTM composite has been obtained by mixing theLa0.7Ca0.2Sr0.1MnO3 and La0.7Te0.3MnO3 manganites with a ratio of 0.5:0.5. All samples havebeen synthesized by using the standard solid state method. In order to investigate themagnetic and magnetocaloric properties of the samples, magnetization measurementsdependence on temperature and magnetic field have been performed by using physicalproperty measurement system. The nature of the magnetic phase transition for all materialshas been identified by using Banerjee criterion and Landau theory and according to bothmethods the magnetic phase transition is second order. Magnetic entropy change values havebeen 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 3.70Jkg-1K-1for 5 T.
