Magnetic Whirlpools Create Their Own Rhythms, Revealing New States of Matter
Scientific news
Researchers modified the properties of a magnetic system not by applying an external periodic field, but by using its own internal oscillations. In a magnetic disk, these oscillations act as a periodic "engine" that changes the behavior of magnetic waves. The researchers referred to this method as self-induced Floquet band engineering.
The present study was carried out in the following CNRS laboratory:
