Dr. Majetich is a Physics Professor at Carnegie Mellon University specializing in magnetic nanoparticles and nanostructures, including both materials preparation and characterization, for potential applications in data storage media, biomedicine, high frequency inductors, permanent magnets, and magnetic refrigeration. She has authored over 100 papers and has three patents. She has received a National Young Investigator Award from the US National Science Foundation for her work, was a 2007 Distinguished Lecturer of the IEEE Magnetics Society, and is a Fellow of the American Physical Society. Her previous work most relevant to the FCRP proposal is in the development of a nanomasking process for pattern transfer into magnetic multilayer films, and the use of conductive atomic force microscopy probes to measure magnetoresistance in individual nanopillars.
