Magnetic tunnel junctions with MgO-EuO composite tunnel barriers
The chalcogenide compound EuO is best known as a highly efficient spin-filter tunnel barrier material. Using the molecular beam epitaxy method, we combine polycrystalline EuO with epitaxial MgO and construct magnetic tunnel junctions with such hybrid tunnel barriers. Tunnel magnetoresistance of over...
