We present theoretical studies of the influence of spin orbit coupling on the
spin wave excitations of the Fe monolayer and bilayer on the W(110) surface.
The Dzyaloshinskii-Moriya interaction is active in such films, by virtue of the
absence of reflection symmetry in the plane of the film. When the magnetization
is in plane, this leads to a linear term in the spin wave dispersion relation
for propagation across the magnetization. The dispersion relation thus assumes
a form similar to that of an energy band of an electron trapped on a
semiconductor surfaces with Rashba coupling active. We also show SPEELS
response functions that illustrate the role of spin orbit coupling in such
measurements. In addition to the modifications of the dispersion relations for
spin waves, the presence of spin orbit coupling in the W substrate leads to a

Ab initio calculations of the local spin polarization at the (0 0 1) surfaces performed on the binary FePd and FeRh alloys are presented. For Rh-terminated FeRh (0 0 1) surface, the calculations indicate a possible magnetic reconstruction leading to a ferromagnetic order in the surface region, in contrast to the AF-II ground state of the infinite bulk FeRh alloy.
