Golam's recent paper entitled "Tuning Dzyaloshinskii-Moriya interaction in ferrimagnetic GdCo: A first-principles approach (link)" published in PRB. In this article, we explore the impact of cap layer composition and different cap layer heavy metals on the Dzyaloshinskii-Moriya Interaction (DMI). We also show the effect of structural arrangements (to mimic the experimentally realistic structures) on the DMI.
