Title:
MAGNETIC LAMINATED FILM, AND MAGNETORESISTIVE EFFECT ELEMENT
Document Type and Number:
WIPO Patent Application WO/2022/265058
Kind Code:
A1
Abstract:
Provided are: a laminated film which enables a writing current to flow, and can achieve a high-density and/or high-speed memory; and a magnetoresistive effect element using the same. A magnetic laminated film 10 comprises: a first ferromagnetic layer 12; an interlayer coupling nonmagnetic layer 10a provided on the first ferromagnetic layer 12; and a second ferromagnetic layer 16 provided on the interlayer coupling nonmagnetic layer 10a, wherein the interlayer coupling nonmagnetic layer 10a has a three-layer structure having a first nonmagnetic layer 13, an interlayer coupling layer 14, and a second nonmagnetic layer 15. The interlayer coupling layer 14 is selected from metals or alloys containing at least Ir, Ru, and Rh. The first nonmagnetic layer 13 and the second nonmagnetic layer 15 are each selected from Pt-containing metals or alloys.
