Research Interests

The research in my group concentrates on understanding the behavior of magnetic, ferroelecctric and multiferroic oxide nanostructures, and in particular on determining the role that interfaces play in controlling this behavior. We are correlating the ferroic and transport properties with microstructure, magnetic domain structure and composition profile, determined using a range of high-resolution electron-microscopy, atomic force microscopy and position-sensitive atom probe techniques, including Lorentz microscopy for imaging magnetic domains and piezoforce microscopy for imaging ferroelectric domains. We are also developing in-situ TEM techniques for the investigation of magnetization reversal and transport behavior.
