Abstract

The microscopic properties of Co/Pd multilayers were studied by ferromagnetic and nuclear magnetic resonance. In addition to previous results the magnetic anisotropy is found to be also a function of the Pd layer thickness, increasing below 20 Å for decreasing thickness. This is ascribed to a decrease in the Pd/Co interface contribution to the anisotropy.

Hyperfine field spectra show a shift to lower hyperfine fields upon decreasing Co sublayer thickness. This is attributed to an expansion of the Co ‘lattice’. Comparison of the results on the [111] multilayers with those on almost single phased [100] multilayers suggests that this expansion is nearly isotropic.
