The elaboration of innovative spintronic devices implies the employment of spin dependent electronic properties of magnetic materials. Growing interest in search and development of promising spintronic materials requires spin-resolved studies. This work reports on the development of spin polarized high resolution hard X-ray photoemission spectroscopy (SPIN HAXPES) at SPring-8. Hard X-ray excitation provides the possibility to study a whole spintronic multilayer device due to the large inelastic mean free path of the photoelectrons at high kinetic energies. The implementation of SPIN HAXPES using a SCIENTA R4000 analyzer equipped with SPLEED detector is discussed. The installation of a phase retarder at BL47XU beamline is considered for studies of magnetic circular dichroism in the core level photoemission and spin-resolved experiments. This work is funded by JST-DfG (Project FE 633/6-1).
