Magnetism is topic of enduring fundamental scientific interest and has had a number of successful and important applications ranging from magnetic resonance to high density information storage. We seek deeper understanding of the behavior of the electronic spin in materials, the magnetic phenomena that arise from collections of spins, and the novel phenomena that emerge in microscopic magnetic structures and in complex materials in which disparate materials controllably interact.
We are developing new approaches to these studies including nanoscale imaging tools and novel approaches to understanding dynamic interactions within and between magnetic structures. Among the techniques we employ to study magnetism and electron spin in many different environments are conventional magnetic resonance spectroscopy, scanning probe Magnetic Resonance Force Microscopy (MRFM), optically-detected magnetic resonance, ferromagnetic resonance, and electrical and optical spin injection.
