Establishing micromagnetic parameters of ferromagnetic semiconductor (Ga,Mn)As
P. Nemec, V. Novak, N. Tesarova +10
(Ga,Mn)As is at the forefront of research exploring the synergy of magnetism with the physics and technology of semiconductors, and has led to discoveries of new spin-dependent phe…
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…
Investigation of Optical Spin Transfer Torque in Ferromagnetic Semiconductor GaMnAs by Magneto-Optical Pump-and-Probe Method
Eva Rozkotova, Petr Nemec, Nada Tesarova +4
We report on magnetization precession induced in (Ga,Mn)As by an optical spin transfer torque (OSTT). This phenomenon, which corresponds to a transfer of angular momentum from opti…
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…
Direct measurement of the three dimensional magnetization vector trajectory in GaMnAs by a magneto-optical pump-and-probe method
N. Tesarova, P. Nemec, E. Rozkotova +7
We report on a quantitative experimental determination of the three-dimensional magnetization vector trajectory in GaMnAs by means of the static and time-resolved pump-and-probe ma…
