Measurement of thes−dAdmixture for Mn in Cu

Abstract

Measurements of the spin-resonance linewidth for Mn in dilute copper alloys provides evidence of the extended nature of the magnetic impurity wave function in the metal and allows a straightforward determination of the $s-d$ admixture $V_{\mathrm{dk}}\simeq 1$ eV. A theoretical treatment of the local moment spin relaxation via the distant impurity spin-orbit interaction is given.
