Preparation of electron-doped La(2-x)CexCuO4 thin films with various Ce doping by dc magnetron sputtering
B. X. Wu, K. Jin, J. Yuan +4
A series of c-axis oriented electron-doped high-Tc superconducting La(2-x)CexCuO4 thin films, from heavily underdoped x=0.06 to heavily overdoped x=0.19, have been synthesized by d…
Anomalous flux quantization and formation of dipole-flux state in a multiply-connected high-Tc NdBa2Cu3O7-d superconductor
K. S. Yun, I. Iguchi, S. Arisawa +1
High-resolution scanning superconducting quantum interference device (SQUID) microscopy was used to study the flux quantization phenomenon in multiply-connected anisotropic high-Tc…
Periodic Oscillations of Josephson-Vortex Flow Resistance in Oxygen-Deficient Y1Ba2Cu3Ox
M. Nagao, S. Urayama, S. M. Kim +9
We measured the Josephson vortex flow resistance as a function of magnetic field applied parallel to the ab-planes using annealed Y1Ba2Cu3Ox intrinsic Josephson junctions having hi…
Periodic oscillations of flux flow resistance in intrinsic Josephson junctions with various lateral sizes down to a size of non-linear core of Josephson vortex
S. Urayama, T. Hatano, H. B. Wang +3
To investigate in-phase structures (rectangular lattice) of Josephson vortex lattice (JVL) in intrinsic Josephson junctions (IJJs) of Bi2Sr2CaCu2O8+d, we fabricated IJJs with vario…
Advantage on Superconductivity of Heavily Boron-Doped (111) Diamond Films
Hitoshi Umezawa, Tomohiro Takenouchi, Yoshihiko Takano +8
The superconductivity transition temperatures Tc(onset) of 11.4 K and Tc(offset) of 7.4 K, which are the highest in diamond at present, are realized on homoepitaxially grown (111)…
Fiske steps studied with flux-flow resistance oscillation in a narrow stack of Bi2Sr2CaCu2O8+d junctions
S. M. Kim, H. B. Wang, T. Hatano +6
We have experimentally investigated the fluxon dynamics in a narrow Bi2Sr2CaCu2O8+d stack with junction length L~1.8 um. As an evidence of high-frequency excitation by a collective…
