Title:

FERROMAGNETIC INSULATING MATERIAL AND MANUFACTURING METHOD AND USE THEREOF

Document Type and Number:

WIPO Patent Application WO/2019/232839

Kind Code:

A1

Abstract:

Provided are a ferromagnetic insulating material and a manufacturing method and use thereof. The ferromagnetic insulating material has a structural formula of BiFexOy, wherein x has a given value range of 2-3, and y has a given value range of 4-6. The ferromagnetic insulating material BiFexOy has ferromagnetism at a temperature ranging from 0℃ to 200℃. The ferromagnetic insulating material has a very high saturation magnetization and exhibits significant magnetic anisotropy. The ferromagnetic insulating material BiFexOy exhibits ferromagnetism in an out-plane direction, can be used to manufacture various devices, and has a wide range of applications.
