Investigation of phase-slip-like resistivity in underdoped YBCO
Maher M. Abdelhadi, J. A. Jung
We investigated the anomalous peak resistivity below the onset in underdoped YBCO, reminiscent of that observed in 1D wires of conventional superconductors. We performed meas…
Complementary Theories of Energy Gaps in HTSC
J. C. Phillips, J. Jung, D. Shimada +1
We examine experiments on energy gaps in high temperature superconductors (HTSC) in terms of experimental probes that utilize momentum, position, or neither. Experiments on very hi…
Nanodomain Structure and Function in HTSC
J. C. Phillips, J. Jung
The causes of high-temperature superconductivity (HTSC) are still mysterious, although more than 50,000 experiments have studied this subject. The most severe test of any microscop…
Observation of a Universial Low Temperature Limit of the Free Flux Flow Resistivity in Superclean Bi_2Sr_2CaCu_2O_8 Whiskers
Weimin Chen, J. P. Franck, J. Jung
We report peculiar vortex motion in clean BiSrCaCuO single crystals, which reveals nearly linear- resistivity tails extending to low temperatures. The resistivit…
Evidence of Structural Instability Near T*~250 K in the Resistivity of Bi_2Sr_2CaCu_2O_8 Whiskers
Weimin Chen, J. P. Franck, J. Jung
We report anomalous features in the normal-state resistivity of single crystalline Bi_2Sr_2CaCu_2O_8 whiskers near some characteristic temperature T* \~ 250 K. From these varied ox…
