Experimental fitting to the bipolaronic model of the normal-state resistance of Bi_2Sr_2CaCu_2O_8 single crystals
Weimin Chen, J. P. Franck, J. Jung
Normal-state resistance data from Bi_2Sr_2CaCu_2O_8 single crystals were fitted to the (bi)polaronic conduction model, , with satisfactory agreement over…
Various regimes of flux motion in BiSrCaCuO single crystals
Weimin Chen, J. P. Franck, J. Jung
Four regimes of vortex motion were identified in the magnetoresistance of BiSrCaCuO single crystals: (1) thermally activated flux flow (TAFF) in samples with su…
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…
