Low-Field Flux-Flow Resistivity in Bi2.2Sr2Ca0.8Cu2BO8+
Current-voltage characteristics of single crystals of the 84-K superconducting phase Bi2.2Sr2Ca0.8Cu2BO8+ show no threshold behavior in small magnetic fields at 5080 K, despite large zero-field critical currents which are only weakly field-dependent at low temperatures (<20 K). We attribute this to a low-field flux-flow resistivity which shows an empirical scaling behavior near Tc and which we can use to infer some basic properties of the superconductor. This behavior is intrinsic to Bi2.2Sr2Ca0.8Cu2BO8+ and has crucial implications for its technological potential of the compound.
