手征螺旋磁的自旋共振

Spin resonance in chiral helimagnet

Jun-ichiro Kishine, A. S. Ovchinnikov

摘要:

结果表明,对称性破缺机制和元激发的显著特征在电子自旋共振(ESR)谱中表现出来。在平行于和垂直于螺旋轴的磁场作用下,基元激发分别由与旋转对称破缺相关的螺旋磁振子和与平移对称破缺相关的磁扭折晶体声子描述.我们演示了如何区分这些激发的ESR谱。

英文摘要:

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.
