Correspondence on "Controlling the Curie temperature in (Ga,Mn)As through location of the Fermi level within the impurity band" by M. Dobrowolska et al
K. W. Edmonds, B. L. Gallagher, M. Wang +7
Comment on the recent Nature Materials article by M. Dobrowolska et al., arXiv:1203.1852. We present experimental data showing that the Curie temperature and conductivity of high q…
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…
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…
