(2018). Assessment of the relationship between magnetotransport and magnetocaloric properties in nano-sized La0.7Ca0.3Mn1-xNixO3 manganites. Journal of Magnetism and Magnetic Materials. 469. 10.1016/j.jmmm.2018.09.036.0304-8853https://repositorio.pascualbravo.edu.co/handle/pascualbravo/72The effect of Ni2+substitution on the magneto-transport properties and the concomitant relationship with the magnetocaloric function of nano-sizedLa0.7Ca0.3Mn1−xNixO3(x = 0, 0.02, 0.07, and 0.10) perovskite manganites are reported. All the samples were synthesized using the auto-combustion method. X-raydiffraction analysis studies confirmed the phase purity of the synthesized samples. The substitution of Mn3+ions with Ni2+ions in the La0.7Ca0.3MnO3lattice wasalso verified using this technique. Rietveld analysis indicated that the volume of the unit cell increased with increasing Ni2+content. Zero-field-cooled andfield-cooled magnetization showed that all samples underwent a paramagnetic-ferromagnetic phase transition, which was concomitant with a metal-insulator transition.12application/pdfeninfo:eu-repo/semantics/openAccessArticlehttp://purl.org/coar/access_right/c_abf2https://creativecommons.org/licenses/by-nc-nd/4.0/10.1016/j.jmmm.2018.09.036
