A macroscopic origin of the Hall anomaly in the mixed state of type-II superconductors

TL;DR

This paper investigates the Hall anomaly in type-II superconductors' mixed state near the critical temperature, using a macroscopic approach focusing on flux flow and excitations.

Contribution

It introduces a macroscopic explanation for the Hall anomaly, emphasizing flux flow and excitations at low magnetic fields.

Findings

Hall anomaly can occur at low magnetic fields

Macroscopic approach explains Hall voltage behavior near critical temperature

Flux flow and excitations are key factors in the phenomenon

Abstract

The Hall voltage in the mixed state close to the superconducting critical temperature is determined in the framework of the macroscopic approach. Only flux flow and macroscopic excitations motion are taken into account. The Hall anomaly can appear for rather low magnetic field values.
