Femtosecond all-optical coherent control of spin polarization in altermagnets
Kevin Jäckel, Holger Grisk, Niklas Dornquast +5
Altermagnets constitute an emerging materials platform for spintronic technologies by combining compensated magnetic order with ferromagnet-like spin-split electronic bands. Here,…
Non-Volatile Vortex MTJs with Opto-Electrical and Spin-Diode Nonlinearities as Multifunctional Neuromorphic Platforms
Felix Oberbauer, Tristan Joachim Winkel, Clara C Wanjura +6
The human brain achieves exceptional energy efficiency by co-locating memory and processing, yet reproducing this principle in hardware remains challenging because many neuromorphi…
Femtosecond photocurrents by the Dresselhaus bulk spin-galvanic effect in an inversion-asymmetric ferromagnet
Junwei Tong, Zdenek Kaspar, Afnan Alostaz +18
We study ultrafast photocurrents in thin films of a model ferromagnetic metal with broken bulk inversion symmetry, the half-metallic Heusler compound NiMnSb, following excitation w…
Light induced magnetic order
T. Jauk, H. Hampel, J. Walowski +8
Heat and disorder are opponents of magnetism. This fact, expressed in Curie's law established more than a century ago, holds even in the highly non-equilibrium interaction of ultra…
Exploring the impact of the inverse Faraday effect on all-optical helicity-dependent magnetization switching
M. Kohlmann, L. Vollroth, K. Jäckel +7
All-optical helicity-dependent magnetization switching (AO-HDS) is the quickest data recording technique using only ultrashort laser pulses. FePt grains provide an ideal platform f…
Comparative Analysis of THz Signal Emission from SiO/CoFeB/Metal Heterostructures: Wideband and High-Frequency THz Signal Advantage of PtBi-based Emitter
Tristan Joachim Winkel, Tahereh Sadat Parvini, Finn-Frederik Stiewe +3
Spintronic THz emitters have attracted much attention due to their desirable properties, such as affordability, ultra-wideband capability, high efficiency, and tunable polarization…
