Abstract
Enhancement of the saturation magnetization is highly desired for use in the write pole for magnetic recording. There are recent indications that adding small amounts (layers) of Pd to CoFe alloys (multilayers) may enhance their saturation magnetization. In order to investigate this possibility, we have performed ab initio studies of the magnetic properties of CoFe-Pd multilayers and alloys. We consistently find that the addition of Pd raises the CoFe sublattice saturation magnetization but simultaneously decreases the total magnetization
