Nanosized magnetic particles called skyrmions are considered highly promising candidates for new data storage and information technologies. Now, physicists have revealed new behavior involving the antiparticle equivalent of skyrmions in a ferromagnetic material. The researchers demonstrated their findings using advanced computer simulations that can accurately model magnetic properties of nanometer-thick materials. The results, which were obtained by scientists at Uppsala University in Sweden, at Kiel University and Johannes Gutenberg University Mainz in Germany, and at Université Paris-Saclay in France, were recently published in Nature Electronics.
