Effect of Cr Substitution on Magnetic and Magnetocaloric Properties for La0.62Nd0.05Ba0.33MnO3
In this paper, we investigate the structural, magnetic, and magnetocaloric properties of La 0.62 Nd 0.05 Ba 0.33 Mn 1- x Cr x O 3 manganites elaborated by sol gel process. X-ray diffraction analyses confirm that all elaborated samples are crystallized on the rhombohedral perovskite structure with R-...
