Non-collinear magnetic profile in (Rh/Fe1-xCox)2/Rh(001) bilayer probed by polarized soft x-ray resonant magnetic reflectivity

Magnetization configuration in Fe/Rh/Fe0.5Co0.5/Rh(001) can be non-orthogonal due to competition between the anisotropy and the exchange coupling. Soft x-ray resonant magnetic reflectivity allows us to probe the magnetic profile along the growth axis with in-plane and perpendicular magnetization components. By using different modes of acquisition, we show that it is possible to determine separately the magnetic profile of both magnetization components. Measurements at the Co L-3-edge enable us to investigate the magnetism of the alloy layer independently from the layer of Fe. (C) 2012 American Institute of Physics. [doi:10.1063/1.3670507]
