With the aim of obtaining a material with interesting magnetocaloric and optical properties. We prepared by sol–gel method The La0.57Nd0.1Sr0.18Ag0.15CoO3 (LNSACO) compound. This prepared material has a rhombohedral crystal structure with R-3c space group. According to the conventional ZFC and FC processes, magnetization curves as a function of temperature clearly exhibit a paramagnetic/ferromagnetic transition at Tc = 225 K. The observed irreversibility between FC and ZFC modes at the irreversible temperature Ti = 210 K is assigned to the existence of magnetic anisotropy. By adjusting the hysteresis loop using an empirical formula, different magnetic parameters such as the coercive field (), the remanent magnetization the saturation magnetization () and the squareness ratio () are selected. The existence of double coercive field indicates the presence of the exchange bias effect, proving the material’s suitability for a variety of technological applications including spintronic and magnetic head devices. The optoelectronic uses of cobaltite material have been highlighted by a more in-depth study of the refractive index, penetration depth, extinction coefficients. The bandgap values obtained make them good promising candidates for the absorption of visible light.
