By studying the electric charge orbit and spin of the perovskite manganese oxide, it is helpful to understand the physical mechanisms of the change from the insulator to metal and colossal magnetoresistance (CMR) effect.

The colossal magnetoresistance (CMR) of hole doped manganites [RE.sub.1-x] [A.sub.x]Mn[O.sub.3], with RE = La, Nd, and Pr and A = Ba, Sr, Ca, and Pb, is promising magnetoresistance materials in which the change of resistivity by applying magnetic field is so large that this effect is described as colossal.
