Abstract
We have successfully deposited Sr2YRu1-xCuxO6 films. Sr2YRu1-xCuxO6 films on SrTiO3 (100) have c-axis orientation perpendicular to substrate. All measurement results ”in-plane gazing incident X-ray diffraction figures, small angle grazing incident X-ray diffraction figures and Raman spectra” indicate Sr2YRu0.9CuxO6 films have good epitaxy, pure phase and good crystal structures.Magnetic measurements indicate films superconduct at 5 ~ 8 K. Non-uniform distribution of Cu is discovered in EDS, Auger electron spectra and ESCA analyses. SEM and AFM images of films show films have flat surfaces. Sr2YRu0.9CuxO6 films’ carriers are hole-like and Hall coefficients become larger at low temperature.Ion-implantation with Cu is expected to improve the superconductivity of films. The resistivity and magnetic property are strange. Further work is needed.
