Description:
Author(s): N. I. Polushkin, V. Oliveira, R. Vilar, M. He, M. V. Shugaev, and L. V. Zhigilei In magnetic data storage, information can be corrupted by external magnetic fields or thermal fluctuations. A possible solution to both problems is reversibly altering the m a g n i t u d e , rather than direction, of a bit’s magnetization. The authors propose such an alternative memory, based on chemical-order–disorder transformations in thin-film Fe-Al alloys where cycling (writing–erasing–writing) of disorder-induced ferromagnetism is found to occur under short-pulse heat treatments, e.g. laser irradiation, employed in information recording and storage technologies.
