)Sr0.33MnO3 perovskite oxides were prepared at relatively low calcinating temperature of 600℃ and 800℃ for 10h using amorphous complex precursor. Curie temperature(Tc) and magnetocaloric effects(MCE) were investigated. X-ray diffraction(XRD) and electron diffraction(ED) reveal that the resulting products are of pure single-phase rhombohedral perovskite structure. Transmission electron microscopy(TEM......
