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.

Abstract: A logic function device according to an embodiment of the present invention includes one or more function reconfiguring units having magnetization in one direction set by spin torque caused due to an function reconfiguring current, and an output terminal formed at an end thereof; and one or more input units formed on the function reconfiguring unit and having magnetization in the one direction set by spin torque caused due to an input current, wherein an output voltage of the output terminal is determined on the basis of whether a magnetization direction of the function reconfiguring unit and a magnetization direction of the input unit are parallel or anti-parallel.
