The Materials Research Science and Engineering Center (MRSEC) at Johns Hopkins University supports an interdisciplinary research program on nanostructures with enhancd magneto-electronic properties. The research is carried out in one interdisciplinary research group, with appropriate seed projects. Within the IRG one thrust is on the magneto-transport properties of high quality bismuth thin films; another thrust is on ferromagnetic/antiferromagnetic multilayers, and another on nanostructured half-metallic chromium oxide films; two other thrusts highlight electrodeposited one-dimensional structures (nanowires) and patterned structures such as arrays of epitaxially grown interacting chromium oxide dots. The center is engaged in a variety of educational activities, including Research Experiences for undergraduates and Research Experiences for Teachers, an undergraduate fellow program and a high school teacher internship program. The Center supports well maintained shared experimental facilities, which are accessible to outside users and also supports interactive efforts within industry and other sectors.
