  • Patent number: 12106879
    Abstract: 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.

  • Patent number: 11322190
    Abstract: Disclosed is a magnetic device including a spin sinker. The magnetic device includes a storage medium, a spin sinker, and a read node. The storage medium receives an in-plane current from outside and generates a self-generated spin current that perpendicularly flows to a charge current, thereby controlling a data structure with the self-generated spin current. The spin sinker receives and attenuates the spin current. The read node measures a magnetoresistance of a data structure through the storage medium. The storage medium is made of a magnetic metal and the spin sinker is made of a magnetic insulating material.
