Aiming at the problem of predicting that ferromanganese aluminum alloy can replace silicon in electronic products, the Moscow Iron and Steel Institute took the lead in publishing research results in the world. The test did not confirm that ferromanganese aluminum alloy has the property of replacing silicon. The research results were published in the international academic journal "Magnetics and Magnetic Materials".
Ferromanganese aluminum alloys are considered to have potential applications in spin electronics and are modern alternatives to silicon in electronic products. Dmitry Karpinkov, a staff member of the Moscow Iron and Steel Institute who participated in the study, said that finding materials with semi-metallic conduction type is an extremely important task because, according to plan, this material will be applied to spin Electronics. In order to be applied in the spintronics structure, all the magnetic moments of the electrons must be aligned in one direction. This helps increase the effectiveness of the spintronics device.
Foreign researchers have predicted that ferromanganese aluminum alloys have the required conductivity type. Scholars at Moscow Iron and Steel Institute decided to test their theoretical assumptions.
"The sample is extremely disordered and does not have a permanent magnet sequence," Karl Piankov explained. He said the alloy is similar to so-called "bad alloys" in terms of transport properties. For "bad alloys", it is a typical feature to have unusually high electrical resistance compared to ordinary metals.
Researchers plan to continue to look for materials that have 100% spin polarizability, both theoretically and experimentally.
