Anisotropic wavevector-dependent damping of thickness-quantized magnons
Tamara Azevedo, Rostyslav O. Serha, Yannik Kunz +7
Magnon damping is a key factor governing spin-wave transport and nonlinear dynamics of multimode magnon systems. However, many descriptions rely on the assumption of an effective m…
Perspectives on inverse design for AI magnonics
Franz Vilsmeier, Florian Bruckner, Claas Abert +2
Inverse design - specifying a desired functionality and letting a computational algorithm find the optimal structure - has emerged as a powerful paradigm for magnonic device engine…
Ultrafast formation of a large dynamic magnetic soliton
Ondřej Wojewoda, Sina Mayr, Miela J. Gross +17
Nonlinear magnetization dynamics offers a rich variety of phenomena ranging from bistability to chaos. Here, we report the ultrafast formation of a dynamic magnetic soliton in thin…
Quantum State Preparation of Ferromagnetic Magnons by Parametric Driving
