Bridging atomistic spin dynamics methods and phenomenological models of single pulse ultrafast switching in ferrimagnets
Florian Jakobs, Unai Atxitia
We bridge an essential knowledge gap on the understanding of all-optical ultrafast switching in ferrimagnets; namely, the connection between atomistic spin dynamics methods and mac…
Exchange-enhancement of the ultrafast magnetic order dynamics in antiferromagnets
Florian Jakobs, Unai Atxitia
We theoretically demonstrate that the ultrafast magnetic order dynamics in antiferromagnets is exchange-enhanced in comparison to their ferromagnetic counterparts. We provide an eq…
Universal criteria for single femtosecond pulse ultrafast magnetization switching in ferrimagnets
Florian Jakobs, Unai Atxitia
Single-pulse switching has been experimentally demonstrated in ferrimagnetic GdFeCo and MnRuGa alloys. Complete understanding of single-pulse switching is missing due to th…
Intrinsic energy flow in laser-excited 3 ferromagnets
Daniela Zahn, Florian Jakobs, Hélène Seiler +6
Ultrafast magnetization dynamics are governed by energy flow between electronic, magnetic, and lattice degrees of freedom. A quantitative understanding of these dynamics must be ba…
Atomistic spin model of single pulse toggle switching in MnRuGa Heusler alloys
F. Jakobs, U. Atxitia
Single femtosecond pulse toggle switching of ferrimagnetic alloys is an essential building block for ultrafast spintronics. Very different element-specific demagnetization dynamics…
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…
