Title: Innovations of Toshihiko Yaoi
Introduction
Toshihiko Yaoi is a notable inventor based in Kanagawa, Japan. He has made significant contributions to the field of magnetic devices, holding a total of 3 patents. His work primarily focuses on enhancing the performance and stability of magnetic tunneling junctions and magneto-resistance effect devices.
Latest Patents
One of his latest patents is the Magnetic Tunneling Junction Device. This device is capable of displaying a magnetic tunneling effect in a stable manner. Specifically, it consists of a first magnetic metal layer and a second magnetic metal layer connected by a ferromagnetic tunnel junction via an insulating layer. The conductance of the tunnel current is altered by the relative angle of magnetization of these layers. The ferromagnetic tunnel junction features a junction area not larger than 1 x 10 m. To reliably control this junction area, the insulating layer is formed by a first insulating layer for the ferromagnetic tunnel junction and a second insulating layer on top of the first.
Another significant patent is the Magneto-Resistance Effect Device and Magnetic Head. This device achieves stable magneto-resistance characteristics even when the width of a soft magnetic material layer is reduced. It includes a layer of soft magnetic material, a rear end electrode, and a forward end electrode. Magnetic domain stabilizers are arranged on both ends of the soft magnetic material layer, generating a bias magnetic field. This configuration allows the direction of magnetization to be oriented effectively, enhancing the device's performance.
