Research Interests

Professor Dahlberg's primary research interests are in magnetism. His active research program involves a substantial effort in spin transport in magnetic multilayers and films and ferromagnetic/antiferromagnetic exchange coupling. In addition to this work, he is also the Director of the Magnetic Microscopy Center (MMC) at the University of Minnesota. The MMC applies magnetic force microscopy techniques to a variety of outstanding physics problems such as the dynamics of single domain magnetic particles, micromagnetics of domain structures and magnetic logic devices.
