文摘

Moving DWs in PMA material maintain their structure under longitudinal in-plane fields. As a result of longitudinal fields, magnetization in the domains becomes canted. A critical longitudinal field was identified and correlated with the DMI strength. A canted collective coordinate model was developed for DW motion under in-plane fields.
