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

The study by electron di4raction and high resolution electron microscopy of several samples of the system La 0.5 Ca 0.5 MnO 3Ψ , apart from strikingly con5rming the correctness of the orthorhombic perovskite-related unit cell of a+a c (2, b+a c (2, c+2a c for 04 40.25, points to the existence of thr
