Spin resonance in chiral helimagnet
Jun-ichiro Kishine, A. S. Ovchinnikov
TL;DR
This paper explores how electron spin resonance (ESR) can reveal symmetry-breaking mechanisms and elementary excitations in chiral helimagnets, distinguishing between helimagnons and kink crystal phonons under different magnetic field orientations.
Contribution
It demonstrates how ESR spectra can differentiate between excitations related to rotational and translational symmetry breaking in chiral helimagnets.
Findings
ESR spectra reveal helimagnons under parallel magnetic field.
ESR spectra reveal kink crystal phonons under perpendicular magnetic field.
Distinct ESR features correspond to different symmetry-breaking excitations.
Abstract
It is suggested that marked features of symmetry breaking mechanism and elementary excitations in chiral helimagnet come up as visible effects in electron spin resonance (ESR) profile. Under the magnetic field applied parallel and perpendicular to the helical axis, elementary excitations are respectively described by the helimagnon associated with rotational symmetry breaking and the magnetic kink crystal phonon associated with translational symmetry breaking. We demonstrate how the ESR spectra distinguish these excitations.
