Patent number: 12106879Abstract: A nano spintronic device for using the spin current of a ferromagnetic material and the spin current of a heavy metal channel. The device includes a lower channel layer, a free layer, a pinned layer, an insulating film layer, and an upper channel layer. When current flows upon application of power, electrons are divided into +y-polarized spins and ?y-polarized spins in the lower channel layer, thereby generating torque in the free layer. The torque switches the magnetization direction of the free layer to an +y-axis direction or an ?y-axis direction so that the free layer stores magnetization information according to the magnetization direction. When current flows in the upper channel layer, the current flows into the pinned layer so that electrons in the pinned layer are divided into +y-polarized spins and ?y-polarized spins. The insulating layer insulates the free layer and the pinned layer from each other.Type: GrantFiled: November 12, 2021Date of Patent: October 1, 2024Assignee: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGYInventors: Hyun Cheol Koo, Ki Hyuk Han, Dong Soo Han, Ouk Jae Lee, Byoung Chul Min, Hyung Jun Kim
