Spin-injection Hall effect in a planar photovoltaic cell
J. Wunderlich, A. C. Irvine, Jairo Sinova +5
Successful incorporation of the spin degree of freedom in semiconductor technology requires the development of a new paradigm allowing for a scalable, non-destructive electrical de…
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…
Low voltage control of ferromagnetism in a semiconductor p-n junction
M. H. S. Owen, J. Wunderlich, V. Novak +8
The concept of low-voltage depletion and accumulation of electron charge in semiconductors, utilized in field-effect transistors (FETs), is one of the cornerstones of current infor…
K-edge XANES of substitutional and interstitial Mn atoms in (Ga,Mn)As
N. A. Goncharuk, L. Smrcka, J. Kucera +5
This work reports theoretical and experimental study of the X-ray absorption near-edge structure (XANES) at the Mn K-edge in (Ga,Mn)As diluted magnetic semiconductors. The spectra…
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…
