Abstract
An epitaxial film of the Pd-Fe alloy 116 nm thick with an iron concentration varying in depth from 2 at.% to 50 at.% has been synthesized. An experimental depth distribution profile of iron was obtained as a result of stepwise etching of the film surface with Ar+ ions. Profiling showed that, as a result of annealing, the impurity was redistributed in the film, and a layer of the L10-phase with a constant concentration was formed near the film surface. After removal of the L10-phase, the film exhibits easy-plane anisotropy. The study of spin-wave resonance spectra showed the presence of several modes of standing spin waves, the number of which depends on the residual film thickness.
