Magnetization and magnetoresistance of magnetically soft manganite La0.67Sn0.33MnO3

Abstract Magnetic and magnetoresistive properties of polycrystalline ceramic La 0.67 Sn 0.33 MnO 3 (LSMO) were investigated in the temperature range of 5–300 K and at magnetic fields up to 5 T. According to X-ray diffraction, the compound was found to be composed of two phases: 73 at% perovskite-like and 27 at% a pyrochlore-like. It was found that the magnetic and magnetoresistive behavior of the LSMO samples could be attributed to the perovskite phase.
