Unlocking Magnetic Superpowers: Mn5Ge3's Topological Magnons
In the ever-evolving landscape of condensed matter physics, a recent breakthrough has emerged from the collaborative efforts of researchers at the Peter Grünberg Institute (PGI-1), École Polytechnique Fédérale de Lausanne, Paul Scherrer Institut in Switzerland, and the Jülich Centre for Neutron Science (JCNS). This synergetic work, driven by the trio Manuel dos Santos Dias, Nikolaos Biniskos and Flaviano dos Santos and led by Stefan Blügel, Thomas Brückel and Samir Lounis, has delved into unexplored magnonic properties within Mn5Ge3, a three-dimensional ferromagnetic material.
