Magnonic Proximity Effect in Insulating Ferro- and Antiferromagnetic Trilayers
Verena Brehm, Martin Evers, Ulrike Ritzmann +1
The design of spin-transport based devices such as magnon transistors or spin valves will require multilayer systems composed of different magnetic materials with different physica…
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…
Asymmetric skyrmion-antiskyrmion production in ultrathin ferromagnetic films
Ulrike Ritzmann, Louise Desplat, Bertrand Dupé +2
Ultrathin ferromagnets with frustrated exchange and the Dzyaloshinskii-Moriya interaction can support topological solitons such as skyrmions and antiskyrmions, which are metastable…
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…
