Observations were made of the V⁵¹ magnetic resonance shift and line width in chromium -vanadium solid solutions over a wide composition range. The Knight shift varies considerably with composition reaching a maximum value of 0.687% for an alloy cortaining 62% chromium. This may be connected with the appearance of magnetic moments on the Cr atoms. A slight dependence of shift on magnetic field is found and is attributed to second order quadrupole effects. The line width decreases to a value of about 1.5 gauss as the concentration of chromium increases due to the reduction dipolar broadening. A discussion of the field dependence of the line width is given. For vanadium concentrations less than 5% broad transitions appear at which the intensity of the resonance signal decreases. This is attributed to the appearance of antiferromagnetism.
