First realization of an electric circuit with a magnetic insulator using spin waves

Researchers at the University of Groningen, Utrecht University, the Université de Bretagne Occidentale and the FOM Foundation have found that it is possible to make an electric circuit with a magnetic insulator. This was first deemed impossible. The circuit is realized using spin waves: wave-like perturbations in the magnetic properties of a material. Their discovery is interesting for the development of novel, energy-efficient electronic devices, particularly integrated circuits. A device base...
