The spin-resolved analysis of electronic properties of hybrid metal-organic interfaces is of great interest. Metal-organic materials are promising candidates for spintronic applications because of their advantageous properties and chemical flexibility.
Over the past decades, the various forms of photoemission experiments have become one of the standard measurement techniques in surface physics. In contrast to conventional photon optics, an effective spin polarisation analysis of a given electron beam is difficult. Since organic materials also tend to degrade within a short period, a massive reduction of spin-resolved data acquisition time is crucial.
The recently developed multichannel spin- and angle-resolved photoemission spectroscopy[1] solves this issue by enhancing the figure of merit by several orders of magnitudes, making the analysis of spin-transport (e.g. spin diffusion lenght) in metal-organic interfaces possible. Both, the analysis of the novel measurement technique and metal-organic interfaces will lead to new insights and prospects.
