Abstract
Strong magnetic circular dichroism (MCD) in 4f photoemission from rema nently magnetized films of Tb(0001) and TbFe(x) grown on W(110) is rep orted. Asymmetries of up to 62% have been observed for the 4f8-S-2(7/2 ) multiplet component, in agreement with a calculated 93% effect, taki ng into account the incomplete circular polarization of the photon bea m and the experimental geometry. This is a very strong MCD effect and provides interesting perspectives for surface and thin-film magnetism, as well as a versatile sensor for circular polarization of soft x ray s over a wide photon-energy range.
