Description
We report the investigations of electrical magnetic and thermal properties of La0.7-xCexCa0.3MnO3 (0.0 ≤ x ≤ 0.3) manganites. The metal-semiconducting transitions (TMS) are observed for all doped manganites at ∼ 255 K, ∼ 235 K ∼ 220 K and ∼ 154 K. The magnetic susceptibility measurement confirms that the sample undergoes a transition from paramagnetic to ferromagnetic phase at a particular temperature (TC). It is noticed that the TC is nearly equal to TMS. Specific heat measurements depict a pronounced anomaly near the TC, indicating the magnetic ordering and magnetic inhomogeneity in the samples.
