A strong ferroelectric ferromagnet created by means of spin–lattice coupling
2010
Ferroelectric ferromagnets — materials that are both ferroelectric and ferromagnetic — are of significant technological interest. But they are rare, and those that do exist have weak ferroelectric and ferromagnetic properties. Recently a new way of fabricating such materials was proposed, involving strain from the underlying substrate. This route has now been realized experimentally for EuTiO3. The work shows that a single experimental parameter, strain, can simultaneously control multiple order parameters.
