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.
Claims22
A magnetic device including a spin sinker, the magnetic device comprising:
- a storage medium that receives an in-plane current from the outside thereof and generates a self-generated spin current that flows perpendicularly to a charge current that is the in-plane current and controls a data structure with the self-generated spin current;
- a spin sinker that receives the self-generated spin current from the storage medium and attenuates the self-generated spin current;
- and
- a read node that measures a magnetoresistance of the data structure through the storage medium,
- wherein the storage medium is made of a magnetic metal,
- the spin sink is made of a magnetic insulating material, and
- the read node reads data “1” or data “0” according to a presence type of the structure or according to presence or absence of the data structure in the storage medium.
