Chiral magnetism at oxide interfaces

Research

LaAlO3 and SrTiO3 are two well known non‐magnetic insulators, but when LaAlO3 is deposited on SrTiO3 to form a clean LaAlO3/SrTiO3 interface, the interface becomes an ultra‐thin sheet of conductor. Even more surprisingly, the interface exhibits unusual magnetic properties, but the origin of the observed interfacial magnetism is under debate.

Observation of the inverse spin Hall effect in ZnO thin films: An all-electrical approach to spin injection and detection

Research

Discovery: We have observed a large inverse spin-Hall effect (ISHE) in ZnO films grown using Pulsed Laser Deposition. This discovery provides an entirely new means of measuring spin currents in semiconductors.

Bioinspired Design of Reconfigurable, Anisometric and/or Patchy Particles

Research

Guided by hierarchical materials design principles evolved by bacteria, which include the use of curvature-induced strain to dynamically position amphiphiles, proteins and other biomolecules within single cells, IRG3 of the Wisconsin MRSEC has recently recapitulated these design principles
