Long-lived spin waves in a metallic antiferromagnet
G. Poelchen, J. Hellwig, et al.
Discover the fascinating properties of the metallic antiferromagnet CeCo₂P₂, which showcases long-lived magnons in the terahertz regime, a remarkable feat not seen in typical metals. This groundbreaking research, conducted by G. Poelchen, J. Hellwig, M. Peters, D. Yu. Usachov, K. Kliemt, C. Laubschat, P. M. Echenique, E. V. Chulkov, C. Krellner, S. S. P. Parkin, D. V. Vyalikh, A. Ernst, and K. Kummer, and validated through various advanced techniques, opens new avenues for exploring metallic magnetic systems with undamped THz magnons.
