Özet:

 


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.
