摘要：

We have observed isotropic giant magnetoresistance (GMR) in nonmultilayer magnetic systems using granular magnetic solids. We show that GMR occurs in magnetically inhomogeneous media containing nonaligned ferromagnetic entities on a microscopic scale. Thc GMR is determined by the orientations of the magnetization axes, the density, and the size of the ferromagnetic entities.
