摘要	Angular dependent magnetoresistance (AMR) phenomena in Pr(0.7)Ca(0.3)MnO(3) film have been investigated. A transition between cos(2)theta dependent AMR in an insulating state at low fields and sin(2)theta dependent AMR in a metal state at high fields is observed at intermediate fields, depending on the temperature and/or strength of an applied magnetic field. Although the AMR sign evolution process from cos(2)theta dependence to sin(2)theta dependence at low temperature is different from that at high temperature due to existence of ferromagnetic insulator besides charge ordering antiferromagnetic insulator, we believe that such AMR sign evolutions are closely related with magnetic-field-induced ferromagnetic metal percolation behavior.
