中文摘要	Micro-patterning is considered to be a promising way to analyze phase-separated manganites. We investigate resistance in micro-patterned La0.325Pr0.3Ca0.375MnO3 wires with width of 10 mu m, which is comparable to the phase separation scale in this material. A reentrant of insulating state at the metal-insulator temperature T-p is observed and a giant resistance change of over 90% driven by electric field is achieved by suppression of this insulating state. This resistance change is mostly reversible. The I-V characteristics are measured in order to analyze the origin of the giant electroresistance and two possible explanations are proposed.
