| 中文摘要 | A systemic study of magnetoresistance (MR) in manganite perovskite oxide p-n junction is performed with experiment and theoretical calculation. The spin-dependent tunneling current is calculated with a model of double-band barrier and MR with reverse bias is explained as a result of competition between tunneling currents with different spins. The reduction of recombination rate at the interface of heterojunction with magnetic field is proposed to explain positive MR at forward bias. Furthermore, negative MR is predicted to be observed in oxide heterostructure without electron filling in t(2g)down arrow band of manganite at the interface region with both forward and reverse bias.
