The magnetic susceptibility of vanadium-chromium solid solutions

The magnetic susceptibilities of a number of solid solutions of chromium in vanadium have been measured at 20°, 77° and 293°K. The susceptibility at 20°K decreases with concentration from a value of 300 × 10−6 e.m.u./g atom for pure vanadium to 159 × 10−6 e.m.u./g atom for pure chromium. Fine structure is observed in several regions of the susceptibility-composition curve. The temperature dependence of the susceptibility of all the alloys investigated was small. An interpretation of the susceptibility behaviour is given in terms of the collective electron model.
