Computer prediction technique could be paired with new magnetic material
Author:
Although magnets abound in daily life, magnetism is still very rare in metals. At present, it is found that 5% of the known inorganic compounds show some magnetic force. Since part of the magnetic force is only generated at a specific temperature, there are actually very few magnetic materials that can actually be applied in reality. Materials scientists at Duke University have developed a new study that uses computer models to rapidly predict the magnetic properties of new materials.
The research is documented in a recent issue of Science Advances. Scientists selected 55 elements and randomly selected 3 of them for combination. According to the computer model, 14 of the 236,115 possible combinations have the potential to be used as magnetic substances. To confirm the accuracy of the screening, the scientists matched computer models to match two of the substances — one combining cobalt, magnesium and titanium, and the other magnesium, palladium and platinum. According to tests, the two The material does have magnetic and other properties simulated by the computer, especially the cobalt-magnesium-titanium alloy can remain magnetic at extremely high temperatures. It is the first magnetic material that does not contain rare earth metals but has this property. Practical application will also be possible.
"Any of these new magnets could prove useful in the future, but that doesn't really matter," the research team said. "What matters is that rapid prediction techniques are a major revolution in materials science, and that Moving materials science forward will be invaluable."
This prediction project work was supported by Science Foundation Ireland, the European Commission and the National Science Foundation (DGF1106401). But what kind of surprises this technology can bring us in the future, we can only wait and see.
