A.A. Fraerman, O.G. Udalov
TL;DR
This paper theoretically investigates the diode effect in media with helical magnetic structures, highlighting the conditions and mechanisms that produce diode-like behavior.
Contribution
It introduces phenomenological and microscopic theories explaining the diode effect specifically in noncoplanar magnetic media with helical structures.
Findings
Diode effect occurs only in noncoplanar magnetic structures.
Two mechanisms identified: electron spectrum asymmetry and scattering asymmetry.
Theoretical models developed for the diode effect in such media.
Abstract
The volt-ampere characteristics of a medium with helical magnetic structure are theoretically studied. Phenomenological and microscopic theories of a diode effect in such a medium are proposed. Diode effect appears only in the medium with noncoplanar magnetic structure. Two mechanisms for the diode effect are considered. They are electron energy spectrum asymmetry and electron scattering asymmetry.
