Abstract
The magnetic properties of CON clusters (N=1, 13, 19, and 43) embedded in copper matrix are studied using the discrete-variational local-spi n-density-functional method and embedded cluster models. Single Co ato m in Cu is found to be nonmagnetic, while all the rest Co clusters in Cu are still magnetic with reduced moments. Cu atoms in granular Co/Cu system reveal similar spin polarizations to Cu atoms in Co/Cu multila yers as manifested in recent x-ray magnetic circular dichroism measure ments.
