Abstract
⺠Metal doped and non-metal doped perovskite systems with different grain boundary environments are investigated. ⺠Contrary transport behaviors for the LKMO/Ag sample and the LKMO/STO sample at the high and low temperature regimes are reported. ⺠Significant improvement of the room temperature magnetoresistance under low field for the LKMO/Ag sample is observed. ⺠Different roles of the spin-dependent scattering and the spin-polarized tunneling mechanisms at different temperature regimes are analyzed in detail.
