Abstract:
1. A tunneling magnetoresistive effect element comprising: a recording layer formed of a ferromagnetic thin film having a perpendicular magnetic anisotropy; a pinned layer having a perpendicular magnetic anisotropy and formed of a ferromagnetic thin film having a magnetization direction fixed in one direction; an MgO (001) crystal barrier layer disposed between the recording layer and the pinned layer; a first CoFeB bcc (001) oriented layer disposed at a substrate-side interface of the barrier layer; a second CoFeB bcc (001) oriented layer disposed at an interface of the barrier layer on an opposite side to the substrate; a first intermediate layer disposed at an interface of the first CoFeB layer on an opposite side to the barrier layer, and a second intermediate layer disposed at an interface of the second CoFeB layer on an opposite side to the barrier layer, wherein the first and second intermediate layers comprise one of, or an alloy comprising one of, Pt, Os, V, Cr, Rh, and Re.
