TL;DR
This paper reports a significant asymmetry in magnetoresistance observed in NbSe3 crystals when subjected to a perpendicular magnetic field, persisting across various temperatures and emerging at a specific magnetic induction related to quantum effects.
Contribution
It reveals a novel asymmetry in magnetoresistance linked to quantum limit conditions in NbSe3, expanding understanding of quantum transport phenomena in layered materials.
Findings
Asymmetry of magnetoresistance observed in NbSe3 crystals.
Effect persists over a wide temperature range.
Asymmetry appears above a critical magnetic induction at 4.2 K.
Abstract
A pronounced asymmetry of magnetoresistance with respect to the magnetic field direction is observed for NbSe crystals placed in a magnetic field perpendicular to their conducting planes. It is shown that the effect persists in a wide temperature range and manifests itself starting from a certain magnetic induction value , which at K corresponds to the transition to the quantum limit, i.to the state where the Landay level splitting exceeds the temperature.
