We report measurements of the electrical resistivity and magnetoresistivity of Fe/sub 80//sub X//sub (//sub h//sub y//sub x/Cr/sub x/B/sub 20/ (0less than or equal toxless than or equal to32) from 60 mK to 300 K and in magnetic fields up to 4.3 T. The results show the presence of two effects: one of nonmagnetic origin, associated with electron-electron interaction in a highly disordered system, and the other of magnetic origin, probably due to the Kondo effect and spin fluctuations. The high-field, isotropic magnetoresistivity is examined in detail and shown to be quantitatively inconsistent with the currently available models.
