Electric control of magnetism at the Fe/BaTiO3 interface

Using electric fields for magnetic writing is a very appealing opportunity, however, bulk multiferroic materials at room temperature have not been yet found. Instead, interfacial magnetoelectric coupling could be a viable path to achieve electrical writing of magnetic information in spintronic devices.

Here, we report on a room temperature ON-OFF electrical switching of the interfacial magnetization at the Fe/BaTiO3 interface.
