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…
