Abstract :

A polycrystalline colossal magnetoresistive (CMR) manganite Ce0.7Sr0.3MnO3 was prepared by solid state reaction method and characterized using powder X-ray diffraction. The sample shows single phase orthorhombic structure. The electrical resistivity measurements were done employing four-probe method in the temperature range 70 K - 300 K.
