Hall anomaly and vortex charge in Bi${}_2$Sr${}_2$CaCu${}_2$O${}_x$

Abstract

We present a systematic study of the Hall conductance in Bi${}_2$Sr${}_2$CaCu${}_2$O${}_x$ (Bi2212) thin films over a large range of doping. We find that in a large part of the phase diagram the Hall coefficient changes sign as a function of temperature in the flux-flow regime. By comparing data from many samples, we show that the sign reversal is tied to the superconducting transition and is not a result of a competing order. We then compare our data to the predictions of the Bardeen-Stephan model and show that in all samples there is an additional negative contribution to the Hall conductivity. We extract from the negative excess Hall a vortex-charge that is found to be strongly doping dependent.
