A search for non-reciprocal magnons in MnPS${}_3$

Abstract

Recent articles have suggested that the quasi-two dimensional antiferromagnet MnPS${}_3$ may have non-reciprocal magnons, whereby magnons in a Brillouin zone corner at +q have different energies than those at $-$q. The magnons along the Brillouin zone boundaries were measured using neutron three-axis spectrometry, paying careful attention to the resolution function, to determine whether such non-reciprocity was present. The data show that, within the resolution, there are no significant differences between the magnons in opposite Brillouin zone corners.
