Abstract
The magnetizations of bcc α‐phase iron‐gallium and iron‐arsenic alloys have been measured by a force technique between room temperature and 8°K. Customary extrapolation procedures were used to obtain mean atomic magnetic moments from these data. The linear rate of decrease of mean moment with solute concentration was found to be 1.428±0.095μB per atom for the iron‐gallium system and 1.403±0.143μB per atom for the iron‐arsenic system. This is in contrast with the usual behavior of nontransition metal solutes which are generally considered to dilute a constant iron moment.
