Magnets could help computers talk to each other more efficiently

Topic: Physics

A researcher at Northeastern University is using magnets to make computers more power efficient. He has developed small-scale magnetic systems that can transmit information between digital systems while using very little power.

Xufeng Zhang, a professor of electrical and computer engineering at Northeastern University, is working on making computers more power efficient. He recently published two papers highlighting his research on small-scale magnetic systems.

Central to Zhang's research are magnons, tiny waves that travel through magnetic materials when they are disturbed. Magnons are a type of quasiparticle that exhibits specific shared behavior. In simple terms, magnons are like tiny waves that occur when electrons in magnetic materials are disturbed.

Zhang is using magnons to develop hybrid magnonic devices that can take advantage of spin waves and other information channels such as microwaves and acoustic waves. These devices have the potential to transmit information between digital systems while using very little power compared to traditional digital systems.

Why It Matters

This research could lead to more efficient computers, which would be beneficial for students in India who use computers for their studies. It could also improve cellular reception on smartphones and make MRI machines more accurate.
