Outline of Final Research Achievements

The aim of this project is the development of hard x-ray photoemission spectroscopy (HAXPES) technique with applying magnetic field. Photoemission spectroscopy measurements under the magnetic field had hardly been performed because the emission angle of the photoelectron is changed largely by the magnetic field, and the measurement is very difficult technically. Using the advantage of the high kinetic energy photoemission in HAXPES and the reduction of leakage field with magnetic circuit, a HAXPES measurement with applying 0.4 T magnetic field with permanent magnet has successfully been done for a magnetic multilayer sample.
