March 12 news, Fast Science and Technology learned from the official website of Shanghai University of Science and Technology, a few days ago, Professor Lu Wei of the School of material Science and Technology of Shanghai University of Science and Technology made important progress in the direction of photon-magneton interaction and strong coupling regulation.

The research team discovered for the first time a new kind of magnetic resonance in ferromagnetic insulator single crystal, which is called light-induced magneton state.This discovery opens up a new dimension for the study of magnetonic electronics and quantum magnetism.

The new strong coupling state of magnetons revealed in the study can greatly change the electromagnetic properties of ferromagnetic single crystals and provide a new idea for the entanglement of photons and magnetons.It plays an important role in promoting the application of magnetons in microwave engineering and quantum information processing.The results were published in KuaiBao, the flagship journal of physics.

Professor Lu Wei's team's discovery broke through the & ldquo; monopoly & rdquo; & ldquo;Walker modes”, which has been in this field for more than 60 years, and discovered new magneton states.Or can be used in radar, communication, wireless information transmission and other fields.

It is understood that the research and development of the chip mainly follows Moore's law, that is, the performance of the chip doubles every 18 months to two years.

After stepping into the post-Moore era blindly reducing the chip manufacturing process is challenged by the limit of ldquo; & the time of doubling the performance of rdquo;, processors is prolonged and technical bottlenecks are encountered.

Spintronics and magnetonics based on the development of magnetic materials are developing rapidly, which provides a way to break through the above limitations.
