ABSTRACT
The intrinsic electroresistance (ER) of polycrystalline Sm0.60Sr0.40Mn1-xFexO3 (0 ≤ x ≤ 0.02) have been investigated by magnetotransport measurements. It is found that the ER increases with x while it is suppressed by a magnetic field. These observations imply that the ER increases dramatically with the inhomogeneity in the samples. The possible mechanisms responsible for the observed behavior are discussed.
