We report detailed dielectric investigations of Pr 1-x Ca x MnO 3 (PCMO, x = 0.5) ceramics, a member of the perovskite manganite family that exhibits a colossal magnetoresistance. Analysis of the electrical conductivity and dielectric constant data revealed that in the low temperature phase, below 4
We have investigated the microstructure formed in association with charge ordering transition in perovskite manganites Pr 0.55 Ca 0.45 MnO 3 (PCMO) and Nd 0.5 Sr 0.5 MnO 3 (NSMO). By optical microscope observation, surface relief is observed below the charge ordering transition temperature T CO (CO
