Abstract
The magnetic susceptibility of vanadium-based solid solutions containing titanium, manganese, iron, cobalt and nickel has been measured, as a function of solute concentration, at 20°, 77° and 293°K. Except for the titanium solutions, which showed a flat maximum at about 5 at.%, the susceptibility decreased smoothly with concentration, the rate of decrease being governed, apparently, by the average electron density of the solutions rather than by the characteristics of the particular solutes. The temperature dependence of the susceptibility was found to be slight except in the case of solutions with high iron contents (above about 20 at.%). These showed signs of Curie–Weiss behaviour. The susceptibility results are interpreted in terms of a collective electron model. (Values for density and hardness of the solutions are also reported.)
