With a total of 3 patents, his work is paving the way for future innovations in magnetic devices.
Latest Patents
One of his latest patents is a "Nano spintronic device using spin current of ferromagnetic material and heavy metal channel." This device is designed to utilize the spin current of both ferromagnetic materials and heavy metal channels. It consists of 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, generating torque in the free layer. This torque switches the magnetization direction of the free layer, allowing it to store magnetization information based on the direction of magnetization.
Another notable patent is a "Magnetic device including spin sinker." This device features a storage medium, a spin sinker, and a read node. The storage medium receives an in-plane current from outside, generating a self-generated spin current that flows perpendicularly to the charge current. This self-generated spin current controls the data structure within the device. The spin sinker is responsible for receiving and attenuating the spin current, while the read node measures the magnetoresistance of the data structure through the storage medium.
