Abstract

Magnetic interactions between Fe layers in Fe(110)/Ag(111) superlattices grown by molecular beam epitaxy have been observed using Mössbauer spectroscopy. By measuring the temperature dependence of the hyperfine field at the Fe layers, characteristics of the spin-wave spectrum can be deduced. As the Ag thickness between layers is increased, the magnetic interaction between Fe layers decreases, and the spin-wave spectrum undergoes a transformation from three-dimensional to quasi-two-dimensional.
