Phys. Status Solidi B (2014)
The front cover schematically shows three important aspects of the experiments. First, the lattice mismatch between ZnO and Al2O3 is reduced by rotating the ZnO lattice by 30°. Second, dilute magnetic doping with cobalt results in phase segregation and the formation of nanometer-sized metallic clusters, as indicated via the bright red contrast of the energy-filtered TEM image (background). Third, the sketched device allows for studying spin transport properties. A spin-polarized current from a magnetic Co electrode is injected into ZnO, and the spin polarization is determined optically via the polarization of reflected photons. The source files for the front cover image were prepared by Matthias Althammer.
