Introduction

Kei Yakushiji is a prominent inventor based in Tsukuba, Japan. He has made significant contributions to the field of magnetoresistive elements and magnetic memory. With a total of 2 patents, his work has advanced the understanding and application of magnetic technologies.

Latest Patents

One of his latest patents focuses on a magnetoresistive element that includes a first magnetic layer with a variable magnetization and an easy-axis in a perpendicular direction to a film surface. This element also features a second magnetic layer with an invariable magnetization and an easy-axis in the perpendicular direction, along with a first nonmagnetic layer positioned between the two magnetic layers. The first magnetic layer is composed of a ferromagnetic material that includes an alloy of cobalt (Co) and either palladium (Pd) or platinum (Pt), which are alternately laminated on an atomically close-packed plane. The C-axis of the first magnetic layer directs the perpendicular direction, allowing the magnetization direction to be altered by a current flowing through the layers.
