Time-resolved observation of magnon splitting into vortex gyration and Floquet spin waves
T. Devolder, R. Lopes Seeger, C. Heins +9
Forced excitations at frequencies in the range of the first order azimuthal spin waves of a magnetic disk in the vortex state are known to scatter into the vortex gyration mode, th…
Coherent control of Floquet-engineered magnon frequency combs
Christopher Heins, Amelie L. Fehrmann, Lukas Körber +5
Frequency combs represent a hallmark of coherence emerging from nonlinear dynamics, where periodic driving organizes energy into a precisely spaced spectral structure. Extending th…
Predicting the future with magnons
Zeling Xiong, Christopher Heins, Thibaut Devolder +5
Forecasting complex, chaotic signals is a central challenge across science and technology, with implications ranging from secure communications to climate modeling. Here we demonst…
Electrical detection of magnons with nanoscale magnetic tunnel junctions
Christopher Heins, Zeling Xiong, Attila Kákay +10
Present information and communication technologies are largely based on electronic devices, which suffer from heat generation and high power consumption. Alternatives like spintron…
Benchmarking a magnon-scattering reservoir with modal and temporal multiplexing
Christopher Heins, Joo-Von Kim, Lukas Körber +3
Physical reservoir computing has emerged as a powerful framework for exploiting the inherent nonlinear dynamics of physical systems to perform computational tasks. Recently, we pre…
Nonreciprocal spin-wave dispersion in magnetic bilayers
C. Heins, V. Iurchuk, O. Gladii +5
Nonreciprocal spin-wave propagation in bilayer ferromagnetic systems has attracted significant attention due to its potential to precisely quantify material parameters as well as f…
