Spin- and angular resolved photoemission spectroscopy has become the key technique for the investigation of electronic properties of promising spintronic materials. In contrast to conventional photon optics, an effective spin polarization analysis of a given electron beam is difficult. Since organic materials tend to degrade within a short period, a massive reduction of spin-resolved data acquisition time is crucial. The recent developed multichannel spin- and angle-resolved photoemission spectroscopy [1] solves this issue by enhancing the figure of merit by several orders of magnitudes. Ir(001) shows high potential for the use as a scattering target in multichannel spin analysis [2]. A new Ir(001) multichannel spin-detection system was constructed and the important quantities and efficiency of the system were determined. Spin- and angle-resolved photoemission spectroscopy of thin iron films on W(110) were performed.
