Ultrafast Terahertz Magnetometry Could Enable Heat-Free Magnetism Control
BIELEFELD, Germany, Sept. 1, 2020 — Physicists have precisely measured the ultrafast change in a magnetic state in materials by observing the emission of terahertz (THz) radiation that accompanies such a change in magnetization. An international research team that included scientists from Bielefeld University, Uppsala University, the University of Strasbourg, the University of Shanghai for Science and Technology, Max Planck Institute for Polymer Research, ETH Zürich, and the Free University Berlin developed and tested
