Exploration of single phase layered perovskites as candidate magnetoelectrics Hasselt University
Magnetoelectric multiferroics show both (ferro)magnetism and ferroelectricity which are strongly coupled, allowing for electric field induced switching of the magnetization. No single phase, room temperature magnetoelectric is currently known, that would allow practical applications based on this phenomenon. Only last year, a new mechanism yielding "hybrid improper ferroelectricity" was theoretically predicted for a layered perovskite Ca3Mn2O7. ...
