Magnetic Behavior of Very Dilute Co in Au

Abstract

We have used nuclear orientation to measure the internal magnetic field at nuclei of Co in dilute Au(Co) alloys for various values of the applied magnetic field. We find $\frac{H_{\mathrm{internal}}}{H_{\mathrm{applied}}}=1.29\mathrm{}\pm 0.11$ at high fields, indicating a relatively large magnetic moment on the Co.
