7/24/17: The Leighton Group has openings for two post-doctoral researchers. One position will focus on magnetic nanoparticles and nanoparticle films, including chemical synthesis, magnetometry, neutron scattering, and magnetotransport measurements. The other will deal with complex oxide bulk crystals and heterostructures, specifically titanates and cobaltites, with a strong emphasis on neutron scattering. Both positions are open immediately. Interested applicants should contact Chris Leighton at "leighton@umn.edu".

4/21/2017: Chris presented at the Materials Research Society (MRS) Spring 2017 Meeting on recent work from the group resolving the "Doping Puzzle" in pyrite (FeS2). 

4/3/17: Chris has recently been appointed as inaugural Editor of the newest addition to the American Physical Society family of journals, Physical Review Materials. This will be a broad scope multidisciplinary journal that fills a gap in the APS portfolio, providing a high quality publication and reference source to the expanding community of physicists, materials scientists, chemists and engineers working in the area of materials research. The first call for papers for Phys. Rev. Materials will be released very shortly, with the first papers being published this summer. More information about the journal can be found here.

Leighton Group Focus

Electronic and magnetic materials are the central focus of our group's research. We study a wide variety of types of materials such as nanostructures, thin films, multilayered heterostructures, and bulk polycrystals and single crystals.

We have interests in several areas including the interplay between electronic transport and magnetism in novel materials, and the study of interfaces between dissimilar materials, particularly metals, oxides, and sulfides. The intention is to focus on topics that are attractive from the viewpoint of fundamental science but lie in close proximity to important technological applications such as information storage and microelectronics.

Each of the projects requires fabrication of magnetic/electronic materials and/or structures, detailed atomic level characterization, and in-depth measurement by numerous techniques, particularly electronic transport, magnetometry, and neutron scattering. The work often requires that collaborations be forged, both within the University of Minnesota and with external investigators.
