Knight Shifts and Magnetic Susceptibilities in V Alloys with Ti, Cr, and Tc

Abstract

Knight shifts, $K_V$, of the ${\mathrm{V}}^{51}$ isotope have been measured in binary alloys of V with Ti, Cr, and Tc. The shifts, $K_{T\mathrm{c}}$, of the ${\mathrm{Tc}}^{99}$ nucleus have been measured over the whole composition range in the V-Tc system together with corresponding magnetic susceptibilities. The results on these bcc alloys indicate that the rigid band approximation is valid and nearly all electrons outside the closed $3p$ or $4p$ shell form a common conduction band with admixtures of $s$ and non-$s$ electronic states. Furthermore, these data augmented by electronic specific-heat measurements indicate that the proportion of electrons having $s$ and non-$s$ character changes with electron concentration within this common conduction band.
