MAGNETICS
New Interface and Thin Film Materials We are studying both (i) novel complex oxide and chalcogenide thin films with a range of functional properties and (ii) functional interfaces created from materials that do not exhibit these functional properties. Selected Publications Magnetic Junction Devices We are developing magnetic junction devices in order (i) to understand the role of interfaces and conduction mechanisms from a fundamental perspective and (ii) to develop new classes of devices from a technological perspective. Selected Publications Magnetic Nanostructures We are interested in the behavior of highly spin polarized oxide materials when geometrically confined to the nanometer length scale. Such studies are of fundamental interest but also have potential applications as future magnetic media or magnetic random access memory.
