Abstract
Transport properties in a PLD La0.5Sr0.5CoO3−δ film are studied by DC and microwave View the MathML source technique. It is found that the microwave conductivity increases by the order of the magnitude at the transition to the ferromagnetic state. This is accompanied by only 10% increase in the DC conductivity. This effect and the DC magnetoresistance data obtained are discussed considering the extrinsic and intrinsic sources of magnetic inhomogeneity in doped cobaltates, including the phase separation.
