Equivalence of the effect of weak magnetic field and current on the resistance of Bi2Sr2CaCu2Ox single crystals below the Berezinskii-Kosterlitz-Thouless transition temperature
Gorlova I. G. , Latyshev Yu. I.
The resistance of Bi2Sr2CaCu20 Λ single crystals in the ab plane below Tc is found to depend equally on the magnetic field (H \\c) and the current (lie) :RozHH 1,1 ■ R<xIa(f'H). The dependence b (Τ J) 7_0 =a(T,H) rt._0 and, in general, changes abruptly at Τ = Tc. The results show that the vortex pairs can be excited by the Meissner currents.
