Phase separation in the vicinity of the surface of -(BEDT-TTF)Cu[N(CN)]Br by fast cooling
N. Yoneyama, T. Sasaki, N. Kobayashi +2
Partial suppression of superconductivity by fast cooling has been observed in the organic superconductor -(BEDT-TTF)Cu[N(CN)]Br by two means: a marked sample size effect…
Macroscopic quantum tunneling in a d-wave high-Tc superconductor
K. Inomata, S. Sato, K. Nakajima +6
There is a wide recognition that Josephson-junction-like structures intrinsic to the layered cuprate high temperature superconductors offer an attractive stage for exploiting possi…
Universal magnetic excitation spectrum in cuprates
J. M. Tranquada, H. Woo, T. G. Perring +5
We have recently used inelastic neutron scattering to measure the magnetic excitation spectrum of La(1.875)Ba(0.125)CuO(4) up to 200 meV. This particular cuprate is of interest bec…
Real space imaging of the metal - insulator phase separation in the band width controlled organic Mott system -(BEDT-TTF)Cu[N(CN)]Br
T. Sasaki, N. Yoneyama, A. Suzuki +3
Systematic investigation of the electronic phase separation on macroscopic scale is reported in the organic Mott system -(BEDT-TTF)Cu[N(CN)]Br. Real space imaging of…
Effects of antiferromagnetic planes on the superconducting properties of multilayered high-Tc cuprates
M. Mori, S. Maekawa
We propose a mechanism for high critical temperature (T_c) in the coexistent phase of superconducting- (SC) and antiferromagnetic (AF) CuO_2 planes in multilayered cuprates. The Jo…
Superconducting Properties under Magnetic Field in NaCoOHO Single Crystal
Takahiko Sasaki, Petre Badica, Naoki Yoneyama +3
We report the in-plane resistivity and magnetic susceptibility of the layered cobalt oxide NaCoOHO single crystal. The temperature dependence of the…
