Polar Kerr Effect Measurements of YBa2Cu3O6+x: Evidence for Broken Symmetry Near the Pseudogap Temperature
Jing Xia, Elizabeth Schemm, G. Deutscher +8
Polar Kerr effect in the high-Tc superconductor \YBCO was measured at zero magnetic field with high precision using a cyogenic Sagnac fiber interferometer. We observed non-zero Ker…
Strain-induced single-domain growth of epitaxial SrRuO3 layers on SrTiO3: a high-temperature x-ray diffraction study
Arturas Vailionis, Wolter Siemons, Gertjan Koster
Temperature dependent structural phase transitions of SrRuO3 thin films epitaxially grown on SrTiO3(001) single crystal substrates have been studied using high-resolution x-ray dif…
Dependence of electronic structure of SrRuO3 and the degree of correlation on cation off-stoichiometry
Wolter Siemons, Gertjan Koster, Arturas Vailionis +3
We have grown and studied high quality SrRuO3 films grown by MBE as well as PLD. By changing the oxygen activity during deposition we were able to make SrRuO3 samples that were sto…
Use of real-time Fourier Transform Infrared Reflectivity as an in situ monitor of YBCO film growth and processing
Gertjan Koster, Jeong-Uk Huh, R. H. Hammond +1
Fourier Transform Infrared (FTIR) spectroscopy has been utilized during high rate E-beam evaporation/deposition of YBa2Cu3O7 (YBCO). The results demonstrate the great utility of FT…
