Complex oxides exhibit a rich variety in their electronic and magnetic properties. Famous members include the correlated oxides such as high temperature superconductors and colossal magnetoresistive oxides (CMR), ferroelectrics, and multiferroics. An even richer spectrum of behaviour can be realized at the epitaxial interface between oxides with different functionalities. Our research focuses on controlling and manipulating of the electronic and magnetic property of complex oxide interfaces. Current projects include examining the interface magnetoelectric coupling between ferroelectrics and correlated oxides, and magnetic anisotropy in oxides via strain or artificial defects engineering.

Materials which exhibit half-metallic ferromagnetism have recently attracted great interest because a high efficiency is expected for spintronic device applications, including tunnel magnetoresistance (TMR) devices. To date there are many materials predicted to be half-metals at room temperature, and among them, the L21 ordered full Heusler alloys Co2MnSi and Co2MnGe are promising candidate for spintronics applications due to their high Curie temperatures, 985 K for Co2MnSi and 905 K for Co2MnGe. For spin-transport processes it is interface rather than bulk properties that are of essential importance, because the TMR ratio is sensitive to the interfaces. Our research focuses on controlling and manipulating of the TMR ratios of these alloys. Current projects include examining the effect of structural defects associated with non-stoichiometry on the electronic and magnetic properties in Co-based Heusler-alloy electrodes, particularly in the interfacial region between the Co2YZ electrode and the tunnel barrier.
