Vacancy effect in both calcium and barium on the physical properties of La0.6Ca0.2Ba0.2MnO3 polycrystalline manganite
چکیده انگلیسی
Using magnetization measurements as a function of magnetic applied field up to 5 T at several temperatures, we deduced the magnetic entropy change ΔSM. The |−ΔSMmax|, under a magnetic field change of 5 T is found to be 2.4; 2.69 and 2.84 Jkg−1K−1 for LCBMO, LC and LB, respectively. The obtained results are compared to calculated ones based on the Landau theory and a good concordance is observed.
