The potential of complex oxide materials for device applications stems from their wide range of functional properties, including magnetism, ferroelectricity, and charge transport effects, a consequence of strong electron-electron and electron-phonon correlations which intimately link charge, spin and lattice distortions. In this talk, I will present recent experimental work on the electronic and magnetic interfacial properties of epitaxial Co3O4 ultrathin films and Fe3O4/BaTiO3 and La1−xSrxMnO3/PZT epitaxial heterostructures, which are engineered to exhibit unusually strong magneto-elastic and magneto-electric effects, respectively. These examples demonstrate that the ability to fabricate hybrid structures from the bottom-up is tremendously promising for both applications and for the study of new physical phenomena.
