At present, although research on transparent magnetic materials has been widely carried out worldwide, this study has developed for the first time transparent strong magnetic materials under room temperature conditions, which is expected to bring revolutionary technological development to industries including electrical, magnetic, and optical equipment.
Recently, Japanese researchers have developed a transparent and strong magnetic thin film material, which is expected to be used in the development of a new generation of transparent magnetic devices that can directly display fuel levels, maps, and other information on car and airplane windshields.
This new material is called nanoparticle material, which is made by mixing nanoscale magnetic metal particles of iron cobalt alloy and insulating material aluminum fluoride.
Researchers have found that dispersing nano iron cobalt alloy in aluminum fluoride medium can simultaneously exhibit both the strong magnetism of iron cobalt alloy and the transparency of aluminum fluoride, and can display high transparency and strong magnetism at room temperature.
Researchers have also found that the transparency of materials can be controlled by a magnetic field, which is a novel magneto-optical effect.
