Bremsstrahlung isochromat spectroscopy with spin-polarized electrons

View publication


We describe the construction and operation of a UHV system for bremsstrahlung isochromat spectroscopy in the x-ray regime (1463 eV) with spin-polarized electrons. The performance of the system is illustrated with measurements on Ni(110). The implications of this new technique to study magnetic properties through the spin-resolved electronic structure of the (near) surface are discussed.
