How to Choose In-plane Ferroelectric Polarization States in Rhombohedral BiFeO_3

摘要

An international team of researchers have devised a way to reliably manipulate the ferroelastic polarization states of rhombohedral multiferroic materials that allows coupling to the strain and magnetic properties of these materials.rn"The control of polarization switching to create different domain patterns with predefined in-plane domain orientations is key to applications which are based on the physical properties of domain walls or on the coupling of ferroic order parameters," said N. Balke of Oak Ridge National Laboratory in explaining the potential impact of their discovery.
