Abstract

Whilst possessing potential for electrically-controlled magnonic applications, the spin cycloid of bulk BiFeO3 is lost in technologically-relevant thin films. Here, the authors demonstrate the stabilization of a long-range spin cycloid in BiFeO3thin films through careful choice of electrostatic and strain conditions during thin film growth.
