Magnetic Whirlpools Create Their Own Rhythms, Revealing New States of Matter

Study in Science shows how tiny magnetic structures can generate exotic quantum-like states on their own. Physicists at the Centre for Nanoscience and Nanotechnology (C2N), working with European collaborators, have discovered a surprising new way to control magnetism at the nanoscale. In a study published in Science, the team shows that microscopic “magnetic whirlpools” can create entirely new states of motion by using their own internal dynamics when …

Making nanodevices energy-autonomous

How can we power ever-smaller devices—such as miniaturized sensors or medical implants—without relying on an external energy source? To meet this challenge, researchers are exploring the properties of materials at the nanoscale. The ANR SCENIC project is part of this effort. Its goal is to gain a better understanding of how electrical charges behave at the surface of semiconductor nanowires, in order to control them more precisely.
