Magnetic Susceptibilities and Nuclear Magnetic Resonance Measurements in V-Fe Alloys

Abstract

Magnetic susceptibilities and nuclear magnetic resonance measurements have been made on V-Fe alloys up to 34 at.% Fe in V. The composition and temperature dependence of the susceptibilities and of the NMR linewidth of ${\mathrm{V}}^{51}$ suggests the appearance of magnetic moments at about 23 at.% Fe. The Knight shifts of ${\mathrm{V}}^{51}$ in the nonmagnetic portion of this alloy system are discussed in terms of the contributions from the Fermi contact term, $\mathrm{sd}$ exchange, and induced orbital paramagnetism.
