Abstract

The charge transport in oxygen-plasma-treated La_0.7Ca _0.3MnO_3-δ was discussed. The resistivity measurement showed that oxygen plasma treatment gave rise to oxygen diffusion into bulk regions. The analysis showed a decrease in Mn³⁺ concentration in oxygen nonstoichiometric La_0.7Ca _0.3MnO_3-δ and in the activation energies of Holstein's small polarons in the paramagnetic region.
