Spin resonance in chiral helimagnet

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.
