Magnetization values for iron-rich alloys with various transition elements

The saturation magnetizations of body-centred cubic solid-solution alloys of iron with titanium, molybdenum, tungsten, technetium and rhenium have been measured between room temperature and 8 °K. Mean atomic magnetic moments (μB/atom) calculated from the data decrease linearly with concentration between 2 and 10 at.% solute. The rates of decrease for the solutes listed above are -3·392, -2·105, -2·044, -1·405 and -1·557 μB per unit of concentration respectively. When the data are plotted as a function of electron concentration they approximately superimpose on an extension of the Slater-Pauling curve. Combination of the magnetization results with the neutron diffraction measurements of Collins and Low shows that, while the solute atoms carry moments antiparallel to those on the iron atoms, the average moment per iron atom is either unchanged or increases slightly.
