Ultrafast all-optical toggle writing of magnetic bits without relying on heat
T. Zalewski, A. Maziewski, et al.
Discover an innovative 'cold' all-optical toggle switching mechanism developed by T. Zalewski, A. Maziewski, A. V. Kimel, and A. Stupakiewicz, which changes magnetization in cobalt-substituted iron garnets without the dependency on heat. This groundbreaking research reveals how ultrafast laser excitation can modify magnetic properties, paving the way for faster and more efficient data storage solutions.
