The Magnetic Films Group creates, explores and produces new insights into novel fundamental physics and novel materials related to magnetic phenomena. We investigate new phenomena and push the boundaries of fundamental understanding of nanostructured magnetic materials while developing potential novel concepts for applications ranging from information technologies to energy conversion.

In order to understand and control the electronic and magnetic properties of these materials, we synthesize thin film heterostructures using a variety of techniques including multi-target sputtering,  e-beam evaporation and oxide- MBE and create complex lithographically patterned devices using these materials.

We focus particularly on emerging new phenomena associated with the interaction between spatial and magnetic length scales, as well as proximity effects. Heterostructures, which integrate ferromagnets, antiferromagnets, superconductors, and insulators bring complexity and richness as a result of interfacial coupling and dimensional confinement.  We seek to understand the ultimate limits of miniaturization and prepare magnetic materials with specifically designed functionalities. 

We have at our disposal cutting-edge characterization tools which include the use of neutron-, synchrotron-, and electron-scattering and microscopy at DOE user facilities, as well as sophisticated in-house magneto-transport and thermo-galvanic measurements, low-temperature high-magnetic-field magnetic force microscopy, broadband ferromagnetic resonance, and spatially resolved Brillouin light scattering microscopy.  This infrastructure enables us to comprehensively investigate magnetization dynamics, magneto-transport phenomena, and interfacial coupling effects.
