| 中文摘要 | Current effect on the transport property of the La0.67Ca0.33MnO3 film has been studied as a function of temperature and magnetic field. The two-lead resistance of the sample shows a strongly asymmetric behavior with respect to current direction after a treatment under a current of the density of similar to 1.6 x 10(5) A/cm(2), and the resistance is much lower in forward direction, the direction of the processing current, than in backward direction. A definite change in current-voltage slope at small but finite forward voltages is observed when alternating the electric field from backward to forward, which is indicative of the presence of two different resistive states corresponding to the two current directions and an energy barrier between these states. The magnetoresistance effect of the two resistive states is significantly different, and it is much stronger for the backward current than for the forward one. This has been proved a combined effect of the inclining of the current-voltage slope and the depression of intermediate energy barrier under magnetic field. The present work suggests a possibility to get a different magnetoresistance via interfacial engineering. (c) 2005 American Institute of Physics. |
