Abstract

The direction of Fe magnetic moments in [Fe(40 Å)/RE(30 Å)] multilayers (RE = Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) was studied by ⁵⁷Fe Mössbauer spectroscopy at 300 K and 4.2 K. The Fe magnetic moments, which are in the film plane at 300 K, turn to the perpendicular direction at lower temperatures in the Fe/Pr, Fe/Nd, Fe/Tb, and Fe/Dy multilayers. The mechanism of the perpendicular magnetic anisotropy is discussed.

Spin-wave excitation and Mössbauer spectrometry of amorphous interface in Tb/Fe multilayer
2009, Journal of Alloys and Compounds
Magnetic properties of Tb(48 Å)/Fe(26 Å) multilayer were studied with Mössbauer spectrometry at different temperatures before and after isothermal annealing at 673 K. For this last case, a significant perpendicular magnetic anisotropy is induced. This phenomenon is related to the existence of an amorphous and homogenous Tb–Fe alloy, located at the interfaces, which is produced by interdiffusion during the heat processing. The thermal evolution of hyperfine field deduced for interfacial Tb–Fe alloy is found to obey the Bloch law. The spin-wave stiffness constant, the distance between nearest magnetic atoms and the exchange parameter A were calculated from the experimental results.
