Abstract
The La0.8Ba0.1Ca0.1Mn0.85Co0.15O3 sample was prepared by polymerization complex sol-gel method. The structural, magnetocaloric and electrical properties were studied. The sample crystallizes in the orthorhombic structure with Pbnm space group. In addition to the experimental study, theoretical approaches were adopted to investigate the magnetocaloric and electrical behavior of this sample. The important parameters such as maximum entropy change, full width at half maximum(δFWHM)and relative cooling power (RCP) were explained qualitatively. The analysis of electrical resistivity data shows the semiconductor behavior in all temperatures, which can be explained by small polaron hopping (SPH) and Mott's variable range hopping (VRH) models.
