“…5(a), which is also the same geometry as the magnetic linear dichroism in the angular distribution (MLDAD) of photoemission spectrum. 42) Namely, when p-polarized SR light impinges onto the sample surface obliquely, the dichroism signal is observed for the M " and M # magnetization directions. Figure 5(b) shows the total yield spectrum of the Fe M edge taken under this experimental geometry.…”

Examples of the application of photoelectron emission microscopy (PEEM) combined with synchrotron radiation excitation are reviewed. In particular, the combination study of PEEM and X-ray magnetic dichroism spectroscopy is very valuable for magnetic domain imaging. According to the demands of the industry, such as the production of magnetic recording media, the application method becomes very important. In this review, several examples of studies using magnetic circular and/or linear dichroism spectroscopy for ferro-and antiferromagnetic materials are introduced. In addition, pump-probe time-resolved PEEM is introduced. These methods allow us to measure the dynamical motion of micro-magnetic structures in mesoscopic size magnets in response to the field pulse in the sub-nanosecond range.

“…In our experiments, the islands are created by heating a flat and well-ordered Co film to above 1000 K. Magnetic Linear Dichroism in photoemission (MLDAD) serves to study the electronic and magnetic properties with linearly polarized VUV synchrotron radiation. Both magnetic circular and linear dichroism in photoemission have already been established as a powerful technique to study the magnetic properties of ferromagnetic solids and thin films [2][3][4]. MCDAD and MLDAD in core level photoemission can be theoretically described in the atomic model picture [5][6][7], where the splitting of the 2p level into sublevels with orbital momentum m l is caused by the electrostatic interaction of the core level with the magnetically polarized valence electrons.…”

This investigation turns its attention to magnetic effects of cobalt islands on a non-magnetic substrate. The preparation technique of MBE enables the creation of flat and well-ordered surfaces of hcp-Co(0001) if the evaporation onto a W(110) crystal is carried out at ambient temperatures. Subsequent heating to about 1000 K causes a phase transition from thin films to islands. The investigations are carried out in VUV photoemission with polarized synchrotron radiation, LEED and Scanning Tunneling Microscopy (STM). We employ the technique of magnetic linear dichroism in the angular distribution of photoemission (MLDAD) from valence bands. The MLDAD effect shows significant differences between a flat cobalt layer and cobalt islands. Variations due to the excitation energies are discussed with respect to a fully-relativistic bulk-band-structure calculation.PACS. 61.46.+w Clusters, nanoparticles, and nanocrystalline materials -75.25.+z Spin arrangements in magnetically ordered materials -75.30.Pd Surface magnetism

“…XMLD can be observed in angle resolved, spin-integrated photoemission experiments for ppolarized light under oblique incidence. 2 The first example of this effect was shown on a thin Fe(001) film, for which the Fe 3p core level peak position and line shape changed when the magnetization of the sample was reversed.…”

We have prepared Fe.Ni-, multilayers on Cu(l 11) in order to learn how to control the structure and magnetism of these thin alloy films, which are relevant to the giant magnetoresistance (GMR) effect used in magnetic disk drive heads. Using the Spectromicroscopy Facility (7.0.1.2) on Undulator Beamline 7.0 at the Advanced Light Source, we have measured X-ray magnetic linear dichroism (XMLD) signals from both Fe and Ni 3p lines for fourteen different thin Ni-Fe alloy films on Cu(1 11), with Fe concentration ranging from 9% to 84% and for a variety of film thicknesses. The Curie temperature for all of these samples was in the range 200K to 500K. For many of these films, the Curie temperature was considerably lower than was previously seen for similar films deposited on Cu(100). For a particular Fe concentration x, the Curie temperature increases with alloy film thickness. For a specific film thickness, the Curie temperature has a maximum near x=0.4.
