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…
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…
Enhanced annealing, high Curie temperature and low-voltage gating in (Ga,Mn)As: A surface oxide control study
K. Olejnik, M. H. S. Owen, V. Novak +4
(Ga,Mn)As and related diluted magnetic semiconductors play a major role in spintronics research because of their potential to combine ferromagnetism and semiconducting properties i…
On the character of states near the Fermi level in (Ga,Mn)As: impurity to valence band crossover
T. Jungwirth, Jairo Sinova, A. H. MacDonald +15
We discuss the character of states near the Fermi level in Mn doped GaAs, as revealed by a survey of dc transport and optical studies over a wide range of Mn concentrations. A ther…
Anisotropic Magnetoresistance components in (Ga,Mn)As
A. W. Rushforth, K. Výborný, C. S. King +11
Our experimental and theoretical study of the non-crystalline and crystalline components of the anisotropic magnetoresistance (AMR) in (Ga,Mn)As is aimed at exploring the basic phy…
