Disentangling magnetic and optical contributions in ultrafast dynamics of antiperovskite non-collinear antiferromagnets
J. Kimak, Tomas Ostatnicky, M. Nerodilova +14
Non-collinear antiferromagnets are a class of spin-polarized antiferromagnets in which chiral spin textures give rise to Berry-curvature-driven phenomena, such as the anomalous Hal…
Ultrafast control of spin order by linearly polarized light in noncollinear antiferromagnetic metals
J. Kimak, M. Nerodilova, K. Carva +15
The non-thermal optical control of magnetic order offers a promising route to ultrafast, energy-efficient information technologies. Although optical manipulation of magnetism in me…
Sub-nanosecond heat-based logic, writing and reset in an antiferromagnetic magnetoresistive memory
M. Surynek, A. Farkas, J. Zubac +9
Thermal logic aims to create thermal counterparts to electronic circuits. In this work, we investigate experimentally the response of an analog memory device based on a thin film o…
Observation of Ultrafast Coherent and Incoherent Spin Torques via Terahertz Spin-Hall Magnetoresistance
P. Kubaščík, R. Schlitz, O. Gueckstock +19
Spin Hall magnetoresistance (SMR) is a cornerstone effect in spintronics, enabling the electrical readout of magnetic states through spin-orbit coupling at interfaces. Despite its…
Quadratic magneto-optical Kerr effect spectroscopy: Polarization variation method for investigation of magnetic and magneto-optical anisotropies
V. Wohlrath, Z. Sadeghi, J. Kimák +7
We present a method for a precise determination of magnetic anisotropy and anisotropy of quadratic magneto-optical response of thin films of ferromagnetic and ferrimagnetic materia…
Picosecond transfer from short-term to long-term memory in analog antiferromagnetic memory device
M. Surynek, J. Zubac, K. Olejnik +9
Previous experiments in compensated magnets have demonstrated a potential for approaching the limit of fastest and least-dissipative operation of digital memory bits. However, the…
Twist-angle tunable spin texture in WSe/graphene van der Waals heterostructures
Haozhe Yang, Beatriz Martín-García, Jozef Kimák +7
Angle-twisting engineering has emerged as a powerful tool for modulating electronic properties in van der Waals heterostructures. Recent theoretical works have predicted the modula…
Terahertz probing of anisotropic conductivity and morphology of CuMnAs epitaxial thin films

Antiferromagnetic CuMnAs thin films have attracted attention since the discovery of the manipulation of their magnetic structure via electrical, optical, and terahertz pulses of el…
Fast optical control of spin in semiconductor interfacial structures
L. Nádvorník, M. Surýnek, K. Olejník +5
We report on a picosecond-fast optical removal of spin polarization from a self-confined photo-carrier system at an undoped GaAs/AlGaAs interface possessing superior long-range and…
Control of antiferromagnetic spin axis orientation in bilayer Fe/CuMnAs films
P. Wadley, K. W. Edmonds, M. R. Shahedkhah +10
Using x-ray magnetic circular and linear dichroism techniques, we demonstrate a collinear exchange coupling between an epitaxial antiferromagnet, tetragonal CuMnAs, and an Fe surfa…
Inertial displacement of a domain wall excited by ultra-short circularly polarized laser pulses
T. Janda, P. E. Roy, R. M. Otxoa +9
Domain wall motion driven by ultra-short laser pulses is a prerequisite for envisaged low-power spintronics combining storage of information in magneto electronic devices with high…
