Kurzbeschreibung (Abstract)
We have grown (00l)-oriented thin films of Eu2-xCexCuO4 on (001) SrTiO3 with cerium composition in the range 0≤x≤0.22 by reactive molecular beam epitaxy and characterized them by X-ray diffraction and transport measurements. A systematic change in the c-axis length upon cerium doping was observed indicating that single-phase films were obtained for the whole doping range up to the solubility limit at x=0.22. Superconductivity appeared within a cerium concentration of 0.14≤x≤0.19. Compared to other electron doped cuprates, the superconducting phase space and maximal critical temperature is reduced, and the point of optimal doping is shifted to a higher doping level.
