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
The perovskite-type La 0.5 Ca 0.5-x Na x MnO 3 (0.05 x 0.2) ceramic samples were prepared using the solid-state reaction at high temperature. The X-ray powder diffraction refinement by means of the Rietveld technique reveals that all our samples are single phase and crystallize in the orthorhombic s
