Skyrmion generating apparatus, skyrmion generating method, and magnetic storage apparatus

摘要

Provided is a skyrmion generation method capable of reducing power consumption when skirmion is generated. In this skyrmion generation method, while applying a magnetic field from the magnetic field generating section 14 to the insulating magnetic body 12 having a chiral crystal structure, an electric field is locally applied to the magnetic body 12 by using the electric field generating section 16 . As a result, skirmion is generated inside the magnetic body 12. It is preferable that the magnetic body 12 is at least partially in the form of a thin film having a thickness within the range of 2 to 300 nm, and the magnetic field generating section 14 can apply a magnetic field substantially perpendicularly to the surface of the magnetic body 12 preferable.
