In-situ epitaxial growth of superconducting La-based bilayer cuprate thin films
I. Tsukada, Y. Nagao, Yoichi Ando
We investigate the epitaxial growth of bilayer cuprate La2CaCu2O6+δusing pure ozone as an oxidant, and find that even the crystal with parent composition without cation substitutio…
Fully Gapped Single-Particle Excitations in the Lightly Doped Cuprates
K. M. Shen, T. Yoshida, D. H. Lu +23
The low-energy excitations of the lightly doped cuprates were studied by angle-resolved photoemission spectroscopy. A finite gap was measured over the entire Brillouin zone, includ…

N. P. Ong, Yayu Wang, S. Ono +2
We present a review of the vortex-Nernst effect in the 3 cuprate families La_{2-x}Sr_xCuO_4, Bi_2Sr_2CaCu_2O_8, and YBa_2Cu_3O_{y}, and discuss the scenario that the superconductin…
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…
Reply to the "Comment on 'Intrinsic tunneling spectra of Bi_2(Sr_{2-x}La_x)CuO_6' "

To better address the heating issue in stacks of intrinsic Josephson junctions, we directly measure temperature of the stack by using a micron-sized thermocouple which is in direct…
Inhomogeneous CuO_{6} Tilt Distribution and Charge/Spin Correlations in La_{2-x-y}Nd_{y}Sr_{x}CuO$_{4} around commensurate hole concentration
A. Gozar, B. S. Dennis, T. Siegrist +2
Phononic and magnetic Raman scattering are studied in LaNdSrCuO with three doping concentrations: x ~ 1/8, y = 0; x ~ 1/8, y = 0.4; and x = 0.01, y = 0.…
Normal-state conductivity in underdoped La_{2-x}Sr_xCuO_4 thin films: Search for nonlinear effects related to collective stripe motion
A. N. Lavrov, I. Tsukada, Yoichi Ando
We report a detailed study of the electric-field dependence of the normal-state conductivity in La_{2-x}Sr_xCuO_4 thin films for two concentrations of doped holes, x=0.01 and 0.06,…
Thermal Conductivity of Pr_{1.3-x}La_{0.7}Ce_xCuO_4 Single Crystals and Signatures of Stripes in an Electron-Doped Cuprate
X. F. Sun, Y. Kurita, T. Suzuki +2
It was recently demonstrated that the anisotropic phonon heat transport behavior is a good probe of the stripe formation in La_{2-x}Sr_xCuO_4 (LSCO) [X. F. Sun {\it et al.}, Phys.…
