Terahertz spin-current transparency through rough interfaces
Jiří Jechumtál, Jakub Zázvorka, Ondřej Novák +8
Spin transport across interfaces is critical for spintronic devices, yet remains difficult to probe on ultrafast timescales. We use terahertz emission spectroscopy on Co|Pt heteros…
Spin-to-charge-current conversion in altermagnetic candidate RuO probed by terahertz emission spectroscopy
J. Jechumtál, O. Gueckstock, K. Jasenský +19
Using the THz emission spectroscopy, we investigate ultrafast spin-to-charge current conversion in epitaxial thin films of the altermagnetic candidate RuO. We perform a quantit…
Altermagnetic variants in thin films of Mn5Si3
Javier Rial, Miina Leiviskä, Gregor Skobjin +17
The altermagnet candidate Mn5Si3 has attracted wide attention in the context of non-relativistic spin physics, due to its composition of light elements. However, the presumed struc…
Anisotropy of the anomalous Hall effect in the altermagnet candidate MnSi films
Miina Leiviskä, Javier Rial, Antonín Badura +15
Altermagnets are compensated magnets belonging to spin symmetry groups that allow alternating spin polarizations both in the coordinate space of the crystal and in the momentum spa…
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…
Even-in-magnetic field part of transverse resistivity as a probe of magnetic transitions
Antonin Badura, Dominik Kriegner, Eva Schmoranzerová +13
The component of the resistivity tensor corresponding to voltage transverse to both an applied current and a magnetic field can be separated into odd and even parts with r…
Circular photogalvanic effects in topological insulator/ferromagnet hybrid structures
T. Schumann, T. Kleinke, L. Braun +12
We study laser driven spin-current effects at ferromagnet/topological-insulator interfaces by two complementary experimental approaches. The DC photocurrent is studied in ferromagn…
Mechanism of Spin-Orbit Torques in Platinum Oxide Systems
Jayshankar Nath, Alexandru Vladimir Trifu, Mihai Sebastian Gabor +16
Spin-Orbit Torque (SOT) Magnetic Random-Access Memories (MRAM) have shown promising results towards the realization of fast, non-volatile memory systems. Oxidation of the heavy-met…
Observation of spin Nernst photocurrents in topological insulators
T. Schumann, N. Meyer, G. Mussler +7
The theoretical prediction of topological insulators in 2007 triggered tremendous interest. They are of fundamental interest because of their topological twist in k-space, which co…
