Making EuO multiferroic by epitaxial strain engineering

Abstract

Magnetoelectric multiferroic are materials where the ferroelectric and magnetic ordering can coexist and be mutually coupled. This phenomenon is called magnetoelectric coupling and can in principle be used to improve magnetoelectric memories or other electric-field-controlled spintronic or magnonic devices. Unfortunately, there are a relatively small number of single-phase multiferroics in nature and their magnetoelectric coupling is lower than needed for many applications.
