Topological and Magnetic Materials


Topological and magnetic materials are among the most exciting systems today. Topological materials have very strong spin-orbit coupling that completely changes the nature of the spin-dependent electronic band structure or the magnetic spin-spin interactions. This enables dissipationless electrical currents in edge channels, spin-charge current conversion, skyrmion magnetic bubbles, and other novel phenomena. Magnetic materials exhibit a variety of complex magnetic ordering and magneto-electric coupling that can be useful for spintronic devices. In our lab, we utilize molecular beam epitaxy (MBE) to synthesize designer materials with atomic-layer precision. This allows us to tailor these various phenomena and generate new behavior by combining properties within layered heterostructures.
