Research Overview

Our research group studies structural, electronic, magnetic, and vibrational properties of bulk materials, surfaces and thin films. We use a broad range of experimental methods including electron spectroscopy, elastic and inelastic electron scattering, and optical techniques including microscopy and polarimetry based on the magneto-optic Kerr effect. We also use synchrotron radiation, primarily for photoemission spectroscopy.
