Discovery of a magnonic supercurrent at room temperature
Supercurrents are known physical phenomena related to the phenomena of superconductivity and superfluidity. Until now, they have only been observed at very low temperatures. Our results about the discovery of a magnonic supercurrent in a YIG film at room temperature were recently published in Nature Physics:
