| 技術摘要 / Our Technology： |
A magnetic structure capable of field-free spin-orbit torque switching includes a spin-orbit coupling base layer and a ferromagnetic layer formed thereon. The spin-orbit coupling base layer is made from a particular crystal material. The ferromagnetic layer has magnetization perpendicular to a plane coupled to the spin-orbit coupling base layer, and is made from a particular ferromagnetic material with perpendicular magnetic anisotropy. The perpendicular magnetization of the ferromagnetic layer is switchable by an in plane current applied to the spin-orbit coupling base layer without application of an external magnetic field. A memory device and a production method regarding the magnetic structure are also provided.
