Abstract

In this paper, we reported the correlation of structure, microstructure, and electrical transport properties of polycrystalline La_0.7(Ba_1-xCa_x)_0.3MnO₃ (x = 0 and 0.03). The materials were synthesized by sol-gel method. These materials have interesting electronic and magnetic properties which are heavily affected by the degree of crystallographic mismatch between the La and Mn sites. By tuning these sites, the double exchange (DE) and Coulomb interactions among Mn ions can be artificially controlled. La_0.7Ba_0.3MnO₃ is one of the strong candidates for application because it has high magnetoresistance and magnetocaloric properties. Doped Ca to the La_0.7Ba_0.3MnO₃ is aimed for reducing its transition temperature to near room temperature and increasing the magnetoresistance and magnetocaloric properties of this material. Jahn-Teller distortion can be linked to core-shell model with the result of percolation model.
