【Abstract】 The explosive increasing of information and the miniaturization of electronic devices demand new recording technologies and materials that combine high density, fast response, long retention time and re-writing capability. High density data storage at nanometer/molecular-scale based on magnetic, optic, or electric bistability has attracted great attention in recent years. Here we report a novel organic thin film of1-Ferrocenyl-2-(l-methyl-4-pyridiniumy1) ethylene nitrate prepared by a vacuum deposition method. The film exhibits both magnetic and electrical bistabilities at room-temperature. Further recording experiments have been performed with a scanning tunneling microscope, which confirmed that the thin film could certainly be applied for nanoscale data storage. This work would provide a new strategy to devise organic multifunctional material for high-density information storage.更多还原
