| Abstract: | The magnetic hyperfine interaction of 60Co in the completely miscible alloy Co x Pd1−x was investigated for different values of x by measuring the nuclear orientation of 60Co as function of temperature and by nuclear magnetic resonance of the oriented 60Co nuclei. A broad resonance signal of Gaussian shape could be observed down to x=60%. The dependence of the mean magnetic hyperfine field on the Co concentration was observed to be linear very similar to that of experimental values of the magnetic moment per atom in the literature. The magnetic hyperfine field and its broad distribution are discussed in a simple model with RKKY interaction. This revised version was published online in September 2006 with corrections to the Cover Date. |
