Magnetic hysteresis in systems presenting perpendicular anisotropy and Dzyaloshinskii-Moriya interaction

Micromagnetic calculations were performed to study the impact of interfacial Dzyaloshinskii–Moriyainteraction (iDMI) on the magnetization reversal process of thin films presenting perpendicular magnetic anisotropy (PMA). Systems characterized by low, intermediary or high PMA were explored. As the parameter that controls the intensity of iDMI is increased, significant modifications in the magnetization loops may be observed, mainly associated with the emergence of magnetic domains. Analysing the magnetization spatial distribution, it is verified that the formation of Néel type domain walls and magnetic skyrmions are favored by iDMI.
