摘要：

Results are presented for the temperature and magnetic field dependence of the resistivity of a number of Nb1-xSi(x) amorphous alloys in the variable-range hopping regime (x = 0.89, 0.90, 0.91). The magnetoresistance is negative and proportional to B in low magnetic fields. Analysis of the magnetoresistance presented is based upon theories of the recent model of an 'oriented path' mechanism.
