Angle-resolved photoemission gives evidence of the half metallicity of magnetite

The half-metallic nature of Fe3O4 has been demonstrated using the state-of-the-art photoemission set-up of the CASSIOPEE beamline. This a crucial result because it shows that the details of the electronic structure of Fe3O4 can be described by band theory and, more specifically, confirms that magnetite might be a material of primary importance for future spintronic devices.
