AbstractThe electron conductance and magnetoresistive effect in phase-separation-induced single-carrier magnetic polaron systems is studied by Monte-Carlo simulation. The simulation reveals the co-occurrence of ferromagnetic transition and insulating metallic transition as a function of temperature. The resistivity above the Curie point can be explained by the small-polaron mechanism and variable-range-hopping picture, while the resistivity far below the Curie point shows the contribution of two-magnon scattering. The electron tunneling behavior is confirmed by the nonlinear I-V behaviors and the as-induced magnetoresistance is discussed. (C) 2002 American Institute of Physics.
