Abstract

The 5p3/2 to 5p1/2 shallow core level branching ratios in different photoemission geometries provide a measure of the magnetic ordering in rare earth overlayers as a result of final state effects in photoemission. This 5p level anisotropy can be used to probe magnetic ordering across the Tb Curie temperature as well as magnetic ordering induced by a ferromagnetic substrate in a paramagnetic overlayer. Results are shown for paramagnetic Tb overlayers on Ni(111). The Ginzberg-Landau theory can be used to accurately model terbium thin films for T>Tc.
