Researchers have developed a transparent, high-intensity magnetic film material that could be used in the future to display information such as oil content and maps directly on the windshields of cars and aircraft.

It is found that the nanometer fe-co alloy is dispersed in the medium of aluminum fluoride, and this structure can exert the strong magnetism of fe-co alloy and the light transmittance of aluminum fluoride at the same time, showing high light transmittance and strong magnetism at room temperature.
The researchers also found that the transparency of the material can be controlled by a magnetic field, a new type of magnetic-optical effect.

The researchers said the research on transparent magnetic materials has been widely carried out around the world, but this study is the first to develop transparent magnetic materials at room temperature, which is expected to bring revolutionary technological development to industries including electrical, magnetic and optical equipment.
