Abstract: It is suggested that marked features of symmetry breaking mechanism andelementary excitations in chiral helimagnet come up as visible effects inelectron spin resonance ESR profile. Under the magnetic field appliedparallel and perpendicular to the helical axis, elementary excitations arerespectively described by the helimagnon associated with rotational symmetrybreaking and the magnetic kink crystal phonon associated with translationalsymmetry breaking. We demonstrate how the ESR spectra distinguish theseexcitations.
