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…
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…
Non-thermal laser induced precession of magnetization in ferromagnetic semiconductor (Ga,Mn)As
P. Nemec, E. Rozkotova, N. Tesarova +7
Non-thermal laser induced spin excitations, recently discovered in conventional oxide and metal ferromagnets, open unprecedented opportunities for research and applications of ultr…
Coherent control of magnetization precession in ferromagnetic semiconductor (Ga,Mn)As
E. Rozkotova, P. Nemec, N. Tesarova +5
We report single-color, time resolved magneto-optical measurements in ferromagnetic semiconductor (Ga,Mn)As. We demonstrate coherent optical control of the magnetization precession…
Light-induced magnetization precession in GaMnAs
E. Rozkotova, P. Nemec, P. Horodyska +7
We report dynamics of the transient polar Kerr rotation (KR) and of the transient reflectivity induced by femtosecond laser pulses in ferromagnetic (Ga,Mn)As with no external magne…
Laser-induced Precession of Magnetization in GaMnAs
E. Rozkotova, P. Nemec, D. Sprinzl +7
We report on the photo-induced precession of the ferromagnetically coupled Mn spins in (Ga,Mn)As, which is observed even with no external magnetic field applied. We concentrate on…
