Abstract

A study of compositionally modulated magnetic films of the form Fe/RE, particularly for RE=Nd and Dy, has been performed by vibrating sample magnetometry, ac susceptibility and x‐ray diffraction. The relationship between the magnetic properties and the layer thickness was studied systematically for X‐A Fe/Y‐A Dy, as the layer thicknesses X and Y were varied from 1.8 to 20 A. The ranges of layer thicknesses required for perpendicular anisotropy were determined. The interface and volume anisotropy energies were estimated for X‐A Fe/Y‐A Nd and the differences in the magnetic properties between X‐A Fe/7‐A Dy and X‐A Fe/7‐A Nd are discussed.
