摘要

The transverse magnetoresistance of stoichiometric and off-stoichiometric polycrystalline samples of the Ni3Al system has been measured over the temperature range 1.2<T<90 K in magnetic fields up to 23 kOe. Negative magnetoresistance was observed in all cases. In samples with Ni concentrations of 75 at.% or greater the magnitude of the magnetoresistance reached a maximum at T=TC. The data are in qualitative agreement with the theoretical predictions of Chang et al. based on a model of the magnetoresistance of an itinerant ferromagnet, but the observed magnetoresistance is considerably larger than predicted.
