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

## Abstract Effects of interface decoration and ac frequency, under which the impedance is measured, on the magnetoelectric property have been experimentally studied for the heterojunctions of La~0.5~Ca~0.5~MnO~3~/SrTiO~3~:Nb and La~0.5~Ca~0.5~MnO~3~/LaMnO~3~(3nm)/SrTiO~3~:Nb. It is found that the
The effect of oxygen content on the electrical transport properties of La 0.4 Ca 0.6 MnO 3--y was studied. Upon decreasing oxygen content, the lattice parameters a, b and c of the samples increase and the electrical resistivity of the samples also increases abruptly, contradicting what is expected i
