Abstract
By employing impedance spectroscopy, switchover of one phase (RLF) into another phase (RHF) is reported with time for polycrystalline La0.40Pr0.10Ca0.50MnO3 compound. An irreversible increase in the impedance is explored in terms of the competition of two coexisting contending phases. An increasing along with switchover tendency of the impedance of RLF with RHF with time is conferred having different kinetics of the two coexisting competing phases. The increase in the resistance of the La0.40Pr0.10Ca0.50MnO3 sample is originated in terms of the polar nature of RHF (O-deficient related traps) and structural as well as trap associated nature of RLF.
