Lattice dynamics and ultrafast energy flow between electrons, spins, and phonons in a 3d ferromagnet
Daniela Zahn, Florian Jakobs, Yoav William Windsor +8
The ultrafast dynamics of magnetic order in a ferromagnet are governed by the interplay between electronic, magnetic and lattice degrees of freedom. In order to obtain a microscopi…
Towards Highly Efficient Polymer Fiber Laser Sources for Integrated Photonic Sensors
Simon Spelthann, Stefanie Unland, Jonas Thiem +9
Lab-on-a-Chip (LoC) devices combining microfluidic analyte provision with integrated optical analysis are highly desirable for several applications in biological oder medical scien…
Unifying femtosecond and picosecond single-pulse magnetic switching in GdFeCo
Florian Jakobs, Thomas Ostler, Charles-Henri Lambert +6
Many questions are still open regarding the physical mechanisms behind the magnetic switching in GdFeCo alloys by single optical pulses. Phenomenological models suggest a femtoseco…
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…
Thermal skyrmion diffusion applied in probabilistic computing
Jakub Zázvorka, Florian Jakobs, Daniel Heinze +11
Thermally activated processes are key to understanding the dynamics of physical systems. Thermal diffusion of (quasi-)particles for instance not only yields information on transpor…
