Summary

Story summary

Researchers at the University of Illinois Urbana-Champaign demonstrated a connection between magnetic spin waves and graphene electrons in Physical Review X.
The work shows that two-dimensional magnetic systems can follow the same equations as graphene electrons.
This could advance microwave technology for wireless networks and enable smaller devices such as microwave circulators.
The team identified nine energy bands in a magnonic crystal, showing behaviors similar to graphene's massless electron waves.
