A scenario to the anomalous Hall effect in the mixed state of superconductors
TLDR
In this article, the authors argue that the motion of vacancies in a pinned vortex lattice may dominate the contribution to the Hall effect in an appropriate parameter regime for a superconductor.Abstract:
We argue that the motion of vacancies in a pinned vortex lattice may dominate the contribution to the Hall effect in an appropriate parameter regime for a superconductor. Based on this consideration a model is constructed to explain the anomalous Hall effect without any modification of the basic vortex dynamic equation. Quantitative predictions are obtained. Present model can be directly tested by an observation of the vacancy motion.read more

Motion of vacancies in a pinned vortex lattice: origin of the Hall anomaly
TL;DR: In this article, it was shown that the Hall anomaly is an effect of the vortex many-body correlation rather than that of an individual vortex, and the Hall conductivity is proportional to the inverse of the magnetic field and to the quadratic of the difference between measured and the transition temperatures.

The sign reversal and scaling relations of Hall anomaly in the mixed state type-II superconductors
TL;DR: In this article, a new model for the anomalous Hall effect in the mixed state of type-II superconductors is presented. But the model is restricted to the case of a single body correlating vortex lattice system and does not consider interstitial vortices.

TL;DR: In this paper, it was shown that the symmetry of the Hall angle is an even function of magnetic field, a phenomenon which can possibly be related to vortex guided motion by defects other than twin boundaries.

TL;DR: The data indicate that ρ xy reveals an intrinsic property of vortex motion, which is similar to that of pinning or thermoelectric effects or else to complicated band structures.
