Title:
GALLIUM FERRITE NANOFIBER, MANUFACTURING METHOD FOR GALLIUM FERRITE NANOFIBER, AND USE OF GALLIUM FERRITE NANOFIBER
Document Type and Number:
WIPO Patent Application WO/2021/109858
Kind Code:
A1
Abstract:
The present invention relates to a gallium ferrite nanofiber, a manufacturing method for the gallium ferrite nanofiber, and use of the gallium ferrite nanofiber. The gallium ferrite nanofiber is a ferroelectric and ferromagnetic gallium ferrite nanofiber having room temperature single-phase multiferroic properties, the chemical formula of the composition thereof is GaxFe2-xO3, the numerical value range of x is 0.6-1.0, and the diameter of the gallium ferrite nanofiber is less than 300 nm. The method comprises the following steps: preparing a gallium ferrite precursor solution by using a sol-gel method; performing electrospinning on a fully aged gallium ferrite precursor solution to obtain a gallium ferrite precursor fiber having a first fiber structure diameter; and performing heat treatment on the gallium ferrite precursor fiber to obtain the gallium ferrite nanofiber. The gallium ferrite nanofiber has the ferroelectricity and ferromagnetism of the room temperature single-phase multiferroic properties, and has a second fiber structure diameter, and the second fiber structure diameter is less than 300 nm. The gallium ferrite nanofiber has both the ferroelectricity and ferromagnetism at room temperature, and can be applied to an electronic device.
