SKYRMION DRIVING METHOD AND DRIVING APPARATUS |
| 摘要 |
A skyrmion driving method that utilizes electric current to make it possible to perform driving ON-OFF control at high speed and to suppress the influence of an inertial effect so that the driving control can be performed further logically. The skyrmion is driven based on a driving amount proportional to a time-integrated value of an electric current density j(t) (Am−2) at a clock time t for a location R(t) of the skyrmion at the clock time t and on a driving amount that is in accordance with a diffusive motion due to thermal fluctuation and increases as a Gilbert attenuation constant increases. |

1. A skyrmion driving method that utilizes electric current to drive a skyrmion, the skyrmion driving method comprising: driving the skyrmion based on a driving amount proportional to a time-integrated value of an electric current density for a location R(t) of the skyrmion at a clock time t and on a driving amount that is in accordance with a diffusive motion due to thermal fluctuation and decreases as a Gilbert attenuation constant decreases. |
