Ultrashort spin-orbit torque generated by femtosecond laser pulses
T. Janda, T. Ostatnicky, P. Nemec +6
To realize the very objective of spintronics, namely the development of ultra-high frequency and energy-efficient electronic devices, an ultrafast and scalable approach to switch m…
Voigt effect-based wide-field magneto-optical microscope integrated in a pump-probe experimental setup
T. Janda, L. Nadvornik, J. Kucharik +4
In this work we describe an experimental setup for spatially-resolved pump-probe experiment with integrated wide-field magneto-optical (MO) microscope. The MO microscope can be use…
A jigsaw puzzle metamaterial concept
V. Nežerka, M. Somr, T. Janda +5
A concept of a planar modular mechanical metamaterial inspired by the nature's principle of local adaptivity is proposed. The metamaterial consists of identical pieces similar to j…
Enhancement of the spin Hall voltage in a reverse-biased planar pn-junction
L. NádvornÃk, K. OlejnÃk, P. NÄmec +5
We report an experimental demonstration of a local amplification of the spin Hall voltage using an expanding depletion zone at a pn-junction in GaAs/AlGaAs Hall-bar microdevices. I…
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…
Nanosecond spin-transfer over tens of microns in a bare GaAs/AlGaAs layer
L. NádvornÃk, P. NÄmec, T. Janda +8
The spin-conserving length-scale is a key parameter determining functionalities of a broad range of spintronic devices including magnetic multilayer spin-valves in the commercializ…
