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…
Curie point singularity in the temperature derivative of resistivity in (Ga,Mn)As
V. Novak, K. Olejnik, J. Wunderlich +8
We observe a singularity in the temperature derivative of resistivity at the Curie point of high-quality (Ga,Mn)As ferromagnetic semiconductors with 's ranging from ap…
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…
Substrate temperature changes during MBE growth of GaMnAs
V. Novak, K. Olejnik, M. Cukr +3
Remarkably big increase of the substrate temperature during the low-temperature MBE growth of GaMnAs layers is observed by means of band gap spectroscopy. It is explained and simul…
Mn incorporation in as-grown and annealed (Ga,Mn)As layers studied by x-ray diffraction and standing-wave uorescence
V. Holy, Z. Matej, O. Pacherova +4
A combination of high-resolution x-ray diffraction and a new technique of x-ray standing wave uorescence at grazing incidence is employed to study the structure of (Ga,Mn)As dilute…
