| 中文摘要 | The electrical transport properties of a heterostructure La0.32Pr0.35Ca0.33MnO3 (LPCM)/Nb doped SrTiO3 (STON) junction were studied. The LPCM film is metallic and ferromagnetic below the Curie temperature (T-c) with a colossal magnetoresistance (MR) effect found around Tc. The junction shows good rectifying property. Negative MR was observed by two-terminal current-voltage ( I- V) curves measurement. However, the sign of the MR depends on temperature and the current applied with the four-probe technique. Positive MR may be attributed to the competition between LPCM MR and the junction MR. A simple model is proposed to interpret the related origin. |
