摘要：

Current-voltage (I-V) relations of Nd-0.5(Ca,Sr)(0.5)MnO3 are investigated near its percolation threshold. Resistivity and I-V relations reveal the unstable nature of Nd-0.5(Ca,Sr)(0.5)MnO3. A large slope change in the I-V curve is observable for low (I<15 mA) applied current by manipulating the applied magnetic field at 85 K. Our results indicate that the external applied current can assist not only an insulator to metal transition but also a metal to insulator transition. (C) 2002 American Institute of Physics.
