Polarization dependence of resonant magneto-optical Kerr effect measured by two types of figure-8 undulators.

The resonant magneto-optical Kerr effect of an Fe nanofilm at the L -edge was investigated by theoretically and experimentally using the polarization controlled undulator. Large values of the Kerr rotation angle ( θ K ) were measured at the L 2 and L 3 absorption edges for both of s - and p -polarized incident lights. Furthermore, the sign changes of θ K depending on the photon energy and the polarization of incident light were also observed. [ABSTRACT FROM AUTHOR]
