Effective exchange interaction for terahertz spin waves in iron layers
Liane Brandt, Ulrike Ritzmann, Niklas Liebing +5
The exchange stiffness is a central material parameter of all ferromagnetic materials. Its value controls the Curie temperature as well as the dynamic properties of spin waves to a…
Ultrafast coherent all-optical switching of an antiferromagnet with the inverse Faraday effect
Tobias Dannegger, Marco Berritta, Karel Carva +4
We explore the possibility of ultrafast, coherent all-optical magnetization switching in antiferromagnets by studying the action of the inverse Faraday effect in CrPt, an easy-plan…
Theory of out-of-equilibrium electron and phonon dynamics in metals after ultrafast laser excitation
Ulrike Ritzmann, Peter M. Oppeneer, Pablo Maldonado
The out-of-equilibrium dynamics of electrons and phonons upon laser excitation are often described by the two-temperature model, which assumes that both subsystems are separately i…
Unveiling domain wall dynamics of ferrimagnets in thermal magnon currents: competition of angular momentum transfer and entropic torque
Andreas Donges, Niklas Grimm, Florian Jakobs +4
Control of magnetic domain wall motion holds promise for efficient manipulation and transfer of magnetically stored information. Thermal magnon currents, generated by temperature g…
High-frequency magnon excitation due to femtosecond spin-transfer torques
Ulrike Ritzmann, Pavel Baláž, Pablo Maldonado +2
Femtosecond laser pulses can induce ultrafast demagnetization as well as generate bursts of hot electron spin currents. In trilayer spin valves consisting of two metallic ferromagn…
Terahertz spin dynamics driven by a field-derivative torque
Ritwik Mondal, Andreas Donges, Ulrike Ritzmann +2
Efficient manipulation of magnetization at ultrashort time scales is of particular interest for future technology. Here, we numerically investigate the influence of the so-called f…
