Abrupt transition in quasiparticle dynamics at optimal doping in a cuprate superconductor system
N. Gedik, J. Orenstein, S. Ono +2
We report time-resolved measurements of the photoinduced change in reflectivity, Delta R, in the Bi2Sr2Ca(1-y)Dy(y)Cu2O(8+delta) (BSCCO) system of cuprate superconductors as a func…
Transport and magnetic properties of GdBaCo_{2}O_{5+x} single crystals: A cobalt oxide with square-lattice CoO_2 planes over a wide range of electron and hole doping
A. A. Taskin, A. N. Lavrov, Yoichi Ando
Single crystals of the layered perovskite GdBaCo_{2}O_{5+x} (GBCO) have been grown by the floating-zone method, and their transport, magnetic, and structural properties have been s…
Achieving fast oxygen diffusion in perovskites by cation ordering
A. A. Taskin, A. N. Lavrov, Yoichi Ando
The oxygen-exchange behavior has been studied in half-doped manganese and cobalt perovskite oxides. We have found that the oxygen diffusivity in Gd_{0.5}Ba_{0.5}MnO_{3-δ} can be en…
Manifestation of the magnetic resonance mode in the nodal quasiparticle lifetime in superconducting cuprates
A. A. Kordyuk, S. V. Borisenko, A. Koitzsch +9
Studying the nodal quasiparticles in superconducting cuprates by photoemission with highly improved momentum resolution, we show that a new "kink" feature in the scattering rate is…
Evidence for CuO conducting band splitting in the nodal direction of Bi-2212
A. A. Kordyuk, S. V. Borisenko, A. N. Yaresko +12
Using angle-resolved photoemission spectroscopy with ultimate momentum resolution we have explicitly resolved the bilayer splitting in the nodal direction of Bi-2212. The splitting…
Intrinsic Hall response of the CuO2 planes in a chain-plane-composite system of YBa2Cu3Oy
Kouji Segawa, Yoichi Ando
The Hall coefficient is measured in YBaCuO untwinned single crystals for a wide range of doping. We show that the Hall conductivity and the Hall angle of the {\it CuO$_…
