Epitaxial Integration of La2/3Sr1/3MnO3 and Fe films by the use of a MgO spacer

In this work, the possibility to obtain epitaxial perovskite/MgO/metal multilayered heterostructures has been demonstrated by sputtering techniques. The films are ferromagnetic at room temperature, with no indication of parasite phases from X-ray diffraction and electron microscopy experiments. We argue that these improvements over most previous works may open new directions for the fabrication of fully epitaxial heterostructures for spintronics. © 2010 American Chemical Society.We acknowledge financial support from the Spanish MICINN (MAT2006-13572-C02-01, MAT2008-06765-C02-01/NAN, MAT2009-08024), CONSOLIDER (CSD2007-00041, CSD2008-00023), and the FEDER program.
