| 发明名称 | Magnetic nanoclusters | ||
| 摘要 | A method for preparing magnetic materials is disclosed. The magnetic materials are prepared by implanting low energy magnetic ions into a substrate and annealing with a charged particle beam. Magnetic materials comprising magnetic nanoclusters in the near-surface region of a substrate are also disclosed. The magnetic materials are useful in, for example, magneto-electronic devices such as magnetic sensors. | ||

| 主权项 | 1. A method for producing a magnetic material, the method comprising the steps of: (a) providing a substrate; (b) implanting low energy magnetic ions into the substrate; and (c) in a chamber at less than atmospheric pressure, heating the implanted substrate with a charged particle beam to a peak temperature, optionally holding the peak temperature for a predetermined time, and decreasing the temperature of the implanted substrate to provide the magnetic material; wherein, during step (b), two or more ions are sequentially implanted. | ||
