| 中文摘要 | In electronically phase-separated Pr0.7Pb0.3MnO3 single crystals, current effects have been investigated systematically by combining voltage-current and specific-heat measurements. Below the metal-insulator transition temperature, the resistance increased with current at first, then decreased when the current was above a threshold value. The critical current deceased with increasing temperature and could be modulated dramatically by applying a magnetic field. By combining heat measurements, we found that Joule heat effects seem not able to be completely responsible for the nonlinear current effects. Self-optimized conducting channels or phase separation induced by the current were proposed to be other possible underlying physical processes. (C) 2006 American Institute of Physics. |
