Drs. Donahue and Porter, of the ITL Applied and Computational Mathematics Division, are recognized for their initiative to improve the state of the art in nanomagnetic modeling, the computational simulation of magnetic phenomena at the nanoscale, within the research community. They have very carefully engineered a software tool that is usable, flexible, adaptable, and extensible. It is now the most widely used nanomagnetics modeling system in the world. More than 2,500 journal articles (11 in Science and Nature) and 18 U.S. patent applications reference use of their system, attesting to the magnitude of its impact on U.S. innovation.
