Photoemission of intermetallics

Journal of Magnetism and Magnetic Materials, 1987
Abstract Photoemission and spin-resolved threshold photoemission data on magnetic intermetallic compounds as e.g., MnP and NiMnSb are reviewed. New data on PtMnSb(100) are presented and discussed in terms of a calculated band structure. Recent spin- and angle-resolved photoemission data on monolayer films of Gd on Fe(100) have allowed to test the ...
