Direct observation of spontaneous magnon coherence at room temperature

Researchers at RPTU University Kaiserslautern-Landau have achieved a key experimental breakthrough: For the first time, the spontaneous macroscopic coherence of magnons—the quantized excitations of magnetic materials—has been directly observed.

These experiments confirm a central prediction of the theory of magnon Bose-Einstein condensates.

Eventually, these findings could open new avenues for signal processing, sensing technologies and information processing.

The study has been published in Nature Physics. ...
