Abstract :
[en] We report in this paper the impact of copper oxide (CuO) on the structural, magnetic, and magnetocaloric properties of Pr2/3Sr1/3MnO3 (PSMO) material. Our samples were synthesized by conventional solid-state reaction. The phase formation with no impurities was verified using the X-ray diffraction (XRD). The magnetic properties measured by Magnetic Properties Measurement System (MPMS) show the impact of the AFM CuO semiconductor on the magnetization and the transition temperature of the composite. The magnetic entropy changes were calculated from the isothermal curve of the magnetization as a function of the magnetic field. It is found that a small amount of copper oxide is enough to enhance the magnetocaloric properties of our materials.
