Electrical resistivity and magnetic properties in la ag mn o nd ag mn o and y ce mn o based manganites

Abstract

One group of fascinating compounds with many potential applications is the mixed valence perovskite manganites The versatility of perovskite manganites for electronic applications is demonstrated by the fact that these materials exhibit wide range of conductivity ranging from highly conducting metallic state to insulating state The discovery of large negative magnetoresistivity in these materials has led to the expectation of potential applications in magnetic storage magnetic sensor and mag
