dc.description.abstract | The Comparaison of the structural, magnetic and magnetocaloric properties of Pr0.6 La0.1M0.3MnO3 (M = Ca, Ba and Mg) compounds have been studied using X-ray diffraction (XRD) and magnetic measurements. Our compounds have been prepared using the Sol-Gel method reaction at room temperature. Rietveld refi nements of the X-ray diffraction patterns reveal that our compounds are single phase and crystallize in the orthorhombic system with Pnma space group. Magnetization measurements versus temperature in a magnetic applied fi eld of 0.05T indicate that samples display a ferromagnetic (FM) - paramagnetic (PM) transition with increasing temperature. The Curie temperature TC is found to be 94 K, 39 K and 64 K for M = Ca, Ba and Mg, respectively. From the magnetization data as a function of magnetic applied fi eld, we have determined the associated magnetic entropy change, the maximum of the magnetic entropy ǀ ǀ and the relative cooling power (RCP) for Pr0.6 La0.1M0.3MnO3 (M = Ca, Ba and Mg) compounds. In the vicinity of TC and in a magnetic applied fi eld of 2 T, ǀ ǀ reached, the values of 0.87 J/kg K, 1.43 J/kg K and 0.79 J/kg K for M = Ca, Ba and Mg, respectively. | ar |
