My current research interests include nanoscale magnetic and electronic phenomena in correlated systems, e.g. colossal magneto-resistive (CMR) manganites, multifunctional multiferroics, layered magnets with extremely large anisotropy, High Tc Cuprates, and the newly discovered HTc iron pnictides. Also, we are interested in systems with strong magneto-elastic coupling, where magnetic ordering is strongly coupled with structural transformations. In addition, we are interested in vortex glasses, vortex dynamics and related phase transitions in type II superconductors. We utilize low temperature-scanning probe microscopy (LT-SPM), including both magnetic force microscopy (MFM) and scanning tunneling microscopy/spectroscopy (STM/STS) to investigate these nanoscale phenomena, and how they evolve as experimental parameters (temperature, magnetic field, stress and etc.) vary. Interested graduate students and postdoc candidates are encouraged to contact me.
