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…
Thermally induced all-optical ferromagnetic resonance in thin YIG films
E. Schmoranzerová, J. Kimák, R. Schlitz +10
All-optical ferromagnetic resonance (AO-FMR) is a powerful tool for local detection of micromagnetic parameters, such as magnetic anisotropy, Gilbert damping or spin stiffness. In…
Magneto-Seebeck microscopy of domain switching in collinear antiferromagnet CuMnAs
Tomas Janda, Joao Godinho, Tomas Ostatnicky +23
Antiferromagnets offer spintronic device characteristics unparalleled in ferromagnets owing to their lack of stray fields, THz spin dynamics, and rich materials landscape. Microsco…
Linear wave dynamics explains observations attributed to dark-solitons in a polariton quantum fluid
P. Cilibrizzi, H. Ohadi, T. Ostatnicky +3
We investigate the propagation and scattering of polaritons in a planar GaAs microcavity in the linear regime under resonant excitation. The propagation of the coherent polariton w…
Systematic study of magnetic linear dichroism and birefringence in (Ga,Mn)As
N. Tesarova, T. Ostatnicky, V. Novak +12
Magnetic linear dichroism and birefringence in (Ga,Mn)As epitaxial layers is investigated by measuring the polarization plane rotation of reflected linearly polarized light when ma…
Spin currents in a coherent exciton gas
A. A. High, A. T. Hammack, J. R. Leonard +8
Spin currents and spin textures are observed in a coherent gas of indirect excitons. Applied magnetic fields bend the spin current trajectories and transform patterns of linear pol…
Observation of Half Quantum Vortices in an Exciton-Polariton Condensate
K. G. Lagoudakis, T. Ostatnicky, A. V. Kavokin +3
Singly quantized vortices have been already observed in many systems including the superfluid helium, Bose Einstein condensates of dilute atomic gases, and condensates of exciton p…
Spin transport of indirect excitons
J. R. Leonard, Y. Kuznetsova, Sen Yang +4
Spin transport of indirect excitons in GaAs/AlGaAs coupled quantum wells was observed by measuring the spatially resolved circular polarization of exciton emission. Exciton spin tr…
Spin transport of indirect excitons in GaAs coupled quantum wells
J. R. Leonard, Sen Yang, L. V. Butov +1
Spin transport of indirect excitons in GaAs/AlGaAs coupled quantum wells was observed by measuring the spatially resolved circular polarization of the exciton emission. The exciton…
