Abstract
La0.65Ca0.35MnO3/La0.7Ca0.2Ba0.1MnO3 (COMPI) and La0.65Ca0.35MnO3/Pr0.5Sr0.5MnO3 (COMPII) composite manganites were prepared using a conventional ceramic double-sintering process. The microstructural, magnetic and magnetocaloric properties of the composites were investigated using scanning electron microscopy (SEM) and vibrating sample magnetometry (VSM). X-ray diffraction analysis using Rietveld refinement shows that the starting La0.65Ca0.35MnO3, La0.7Ca0.2Ba0.1MnO3 and Pr0.5Sr0.5MnO3 manganites are single phases and crystallize in the orthorhombic system with a Pbnm space group. Magnetization measurements versus temperature for each composite reveal two magnetic transition temperatures associated to both manganites, which induces an enlargement of the magnetic entropy change peak. A better relative cooling power (RCP) value of 308 J kg−1 around 280 K is obtained for COMPI and is about 75 % of that observed in pure Gd, which makes our composite a potential candidate for magnetic refrigeration around room temperature
