Abstract
Epitaxial growth of SrRuO 3/CoFe2O 4/La 2/3Sr 1/3MnO 3 trilayers on SrTiO 3 (001) substrates has been successfully achieved using pulsed laser deposition. This trilayer configuration, which consists of two conducting ferromagnetic oxides separated by a thin insulating ferrite film, is a promising candidate for all-oxide magnetic tunnel junctions. Structural analyses carried out using transmission electron microscopy and X-ray diffraction demonstrate a remarkable continuation of the in-plane and out-plane crystallographic relations across the entire structure. Magnetic measurements on SrRuO 3/CoFe2O 4/ La 2/3Sr 1/3MnO 3 trilayers indicate independent magnetic switching in an external magnetic field, which is one of the prerequisites for large tunneling magnetoresistance effects. © 2011 American Chemical Society.
