K. Mibu et al., IRON SPIN DIRECTIONS IN FE RARE EARTH MULTILAYERS BY MOSSBAUER-SPECTROSCOPY/, Journal of magnetism and magnetic materials, 126(1-3), 1993, pp. 343-345
Magnetic structure of Fe/RE multilayers (RE = Y, La, Ce, Pr, Nd, Sm, E
u, Gd, Th, Dy, Ho, Er, Tm, Yb and Lu) was studied by Fe-57 Mossbauer s
pectroscopy. Perpendicular magnetic anisotropy was observed in Fe/Pr,
Fe/Nd, Fe/Eu, Fe/Dy and Fe/Tb multilayers. The mechanism of the magnet
ic anisotropy is briefly discussed.
