Correlated Electrons
& Scanning Probe Microscopy

Research in the Hoffman laboratory revolves around nanoscale imaging of the electronic and magnetic properties of strongly correlated electron materials. We have designed and constructed three low-temperature microscopes to investigate a wide range of materials pictured below.
