From to : Separating multi-particle dynamics by intensity cycling
Pavel Malý, František Trojánek, Petr Malý +1
We address the interpretation of transient spectroscopy signals proportional to average excitation number in terms of discrete number of excitations. Building on our recent intensi…
High harmonic generation in monolayer MoS2 controlled by resonant and near-resonant pulses on ultrashort time scales
Pavel Peterka, Artur O. Slobodeniuk, Tomáš Novotný +5
We report on experimental investigation of nonperturbative high harmonic generation (HHG) in monolayer MoS2 in the ultraviolet spectral region driven by mid-infrared light. We stud…
Noncollinear phase-matching of high harmonic generation in solids
Pavel Peterka, František Trojánek, Petr Malý +1
We propose and experimentally demonstrate a scheme allowing to reach noncollinear phase-matching of high harmonic generation in solids, which may potentially lead to an enhancement…
Ultrafast room-temperature valley manipulation in silicon and diamond
Adam Gindl, Martin Čmel, František Trojánek +2
Some semiconductors have more than one degenerate minimum of the conduction band in their band structure. These minima-known as valleys-can be used for storing and processing infor…
Ultrafast valley-selective coherent optical manipulation with excitons in WSe and MoS monolayers
A. O. Slobodeniuk, P. Koutenský, M. Bartoš +4
Increasing the speed limits of conventional electronics requires innovative approaches to manipulate other quantum properties of electrons besides their charge. An alternative appr…
Comparison of space weathering spectral changes induced by solar wind and micrometeoroid impacts using ion- and femtosecond-laser-irradiated olivine and pyroxene
K. Chrbolková, R. Brunetto, J. Ďurech +8
Space weathering is a process that changes the surface of airless planetary bodies. Prime space weathering agents are solar wind irradiation and micrometeoroid bombardment. These p…
Optical determination of the Neel vector in a CuMnAs thin-film antiferromagnet
V. Saidl, P. Nemec, P. Wadley +12
Recent breakthroughs in electrical detection and manipulation of antiferromagnets have opened a new avenue in the research of non-volatile spintronic devices. Antiparallel spin sub…
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…
Enhancement of the spin Hall voltage in a reverse-biased planar pn-junction
L. Nádvorník, K. Olejník, P. Němec +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…
Nanosecond spin-transfer over tens of microns in a bare GaAs/AlGaAs layer

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…
Comparison of micromagnetic parameters of ferromagnetic semiconductors (Ga,Mn)(As,P) and (Ga,Mn)As
N. Tesarova, D. Butkovicova, R. P. Campion +11
We report on the determination of micromagnetic parameters of epilayers of the ferromagnetic semiconductor (Ga,Mn)As, which has easy axis in the sample plane, and (Ga,Mn)(As,P) whi…
Experimental observation of the optical spin-orbit torque
N. Tesarova, P. Nemec, E. Rozkotova +6
Spin polarized carriers electrically injected into a magnet from an external polarizer can exert a spin transfer torque (STT) on the magnetization. The phe- nomenon belongs to the…
Experimental observation of the optical spin transfer torque
P. Nemec, E. Rozkotova, N. Tesarova +8
The spin transfer torque is a phenomenon in which angular momentum of a spin polarized electrical current entering a ferromagnet is transferred to the magnetization. The effect has…
