Hall effect in NS and SNS junctions
F. Zhou, B. Spivak
TL;DR
This paper investigates the Hall effect in normal metal-superconductor (NS) and superconductor-normal-superconductor (SNS) junctions, revealing temperature-dependent suppression and Josephson-frequency oscillations of the Hall voltage.
Contribution
It introduces a detailed analysis of the Hall effect in NS and SNS junctions, highlighting the suppression at low temperatures and the oscillatory behavior in SNS junctions.
Findings
Hall voltage is significantly suppressed at low temperatures.
Hall voltage in SNS junctions exhibits narrow pulses at the Josephson frequency.
The study provides insights into the interplay between superconductivity and Hall effects.
Abstract
Hall effect in SN and SNS junctions is considered. It is shown that at small temperature the Hall voltage is significantly suppressed as compared to its normal metal value. The time dependence of the Hall voltage in SNS junctions has a form of narrow pulses with the Josephson frequency.
