A two-dimensional interacting magnetic domains model is examined to ex
plain the colossal magnetoresistance (CMR) recently observed in mangan
ese-oxides. Electrons transport properties were studied by using Landa
uer's multichannel transport theory and recursive Green's function tec
hnique. Colossal magnetoresistance shows up in this system. The temper
ature dependence of system's MR is also studied. Copyright (C) 1996 Pu
