Heat-conserving three-temperature model for ultrafast demagnetization of 3d ferromagnets
M. Pankratova, I. P. Miranda, D. Thonig +6
We study the ultrafast magnetization dynamics of bcc Fe and fcc Co using the recently suggested heat-conserving three-temperature model (HC3TM), together with atomistic spin- and l…
Unraveling the connection between high-order magnetic interactions and local-to-global spin Hamiltonian in non-collinear magnetic dimers
Ramon Cardias, Jhonatan dos Santos Silva, Anders Bergman +7
A spin Hamiltonian, which characterizes interatomic interactions between spin moments, is highly valuable in predicting and comprehending the magnetic properties of materials. A de…
Metaheuristic conditional neural network for harvesting skyrmionic metastable states
Qichen Xu, I. P. Miranda, Manuel Pereiro +8
We present a metaheuristic conditional neural-network-based method aimed at identifying physically interesting metastable states in a potential energy surface of high rugosity. To…
Transmon probe for quantum characteristics of magnons in antiferromagnets
Vahid Azimi-Mousolou, Anders Bergman, Anna Delin +4
The detection of magnons and their quantum properties, especially in antiferromagnetic (AFM) materials, is a substantial step to realize many ambitious advances in the study of nan…
Adiabatic magnon spectra with and without constraining field: Benchmark against an exact magnon spectrum
Simon Streib, Ramon Cardias, Manuel Pereiro +5
The spectrum of magnon excitations in magnetic materials can be obtained exactly from the transverse dynamic magnetic susceptibility, which is however in practice numerically expen…
Uncovering the role of the light-induced reduction of the inter-atomic exchange in the ultrafast demagnetization of Fe, Co, and Ni
Philippe Scheid, Julius Hohlfeld, Gregory Malinowski +6
Time resolved measurements of the linear magneto-optical Kerr rotation reveal that, in the {\it 3d} ferromagnets Fe, Co and Ni, the amplitude of the demagnetization increases linea…
