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 in the future.
Researchers from institutions such as the Japan Institute of Electromagnetic Materials and Tohoku University recently reported in the British journal Scientific Reports that 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.
Researchers say that although research on transparent magnetic materials has been widely conducted globally, this study is the first to develop transparent strong magnetic materials at room temperature, which is expected to bring revolutionary technological development to industries including electrical, magnetic, and optical equipment.
