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…
Vorticity and the Nernst Effect in Cuprate Superconductors
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' "
A. Yurgens, D. Winkler, T. Claeson +2
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…
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.…
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$_…
Heat transport of LaEuCuO and LaEuSrCuO single crystals
X. F. Sun, Seiki Komiya, Yoichi Ando
To study the rare-earth doping effect on the phonon heat transport of La-based cuprates and shed light on the mechanism of phonon scattering, both -plane and c-axis thermal con…
Anisotropic Magnetoresistance in Lightly Doped La_{2-x}Sr_{x}CuO_{4}: Impact of Anti-Phase Domain Boundaries on the Electron Transport
Yoichi Ando, A. N. Lavrov, Seiki Komiya
Detailed behavior of the magnetoresistance (MR) is studied in lightly doped antiferromagnetic La_{1.99}Sr_{0.01}CuO_{4}, where, thanks to the weak ferromagnetic moment due to spin…

In-plane and out-of-plane thermal conductivities (κ_{ab} and κ_{c}) are measured on single crystals of pure, 1%-hole-doped, and 1%-Zn-doped La_{2}CuO_{4}. The roles of magnons and…
Freezing of stripes in lightly-doped La_{2-x}Sr_{x}CuO_{4} as manifested in magnetic and transport properties of untwinned single crystals
A. N. Lavrov, Seiki Komiya, Yoichi Ando
Resistivity and magnetization measurements are used for studying the transverse sliding of AF domain boundaries in lightly doped La_{2-x}Sr_{x}CuO_{4}. We discuss that it is the fr…

Magnetic-Field-Induced Localization of Quasiparticles in Underdoped LaSrCuO Single Crystals
X. F. Sun, Seiki Komiya, J. Takeya +1
Magnetic-field-induced ordering of electrons around vortices is a striking phenomenon recently found in high- cuprates. To identify its consequence in the quasiparticle dynami…
