TL;DR: In this paper, a detailed discussion about the origin of this frequency difference is reported, which concludes that this is due to the interface Dzyaloshinskii-Moriya interaction (IDMI).
Probing the Dzyaloshinskii-Moriya interaction in CoFeB ultrathin films using domain wall creep and Brillouin light spectroscopy
