Abstract
It hes recently been shown that spin-resolved valence band photoemission spectra can be obtained from macroscopically non-magnetic transition metal materials. This is achieved by combining circularly polarized soft X-rays, electron spin detection and 2p3/2 (L3) resonant photoemission. These experiments have been preformed at the European Synchrotron Radiation Facility (ESRF) by combining a helical undulator, HELIOS I, a 'Dragon' spherical grating monochromator and the new York University (NYU) spin-resolved spectrometer, specifically designed for soft-X-ray photoemission experiments. Examples will be given of applications to antiferromagnetic materials (e.g. CuO) and paramanets (e.g. nickel metal above its Curie temperature).
