Mapping of quantum well eigenstates with semimagnetic probes
Ł. Kłopotowski, A. Gruszczyńska, E. Janik +4
We present results of transmission measurements on CdTe quantum wells with thin semimagnetic CdMnTe probe layers embedded in various positions along the growth axis. The presence o…
Optical spin pumping of modulation doped electrons probed by a two-color Kerr rotation technique
H. Hoffmann, G. V. Astakhov, T. Kiessling +5
We report on optical spin pumping of modulation electrons in CdTe-based quantum wells with low intrinsic electron density (by 10^10 cm^{-2}). Under continuous wave excitation, we r…
Magnetic and chemical nonuniformity in Ga[1-x]Mn[x]As films as probed by polarized neutron and x-ray reflectometry
B. J. Kirby, J. A. Borchers, J. J. Rhyne +9
We have used complementary neutron and x-ray reflectivity techniques to examine the depth profiles of a series of as-grown and annealed Ga[1-x]Mn[x]As thin films. A magnetization g…
Engineering of spin-lattice relaxation dynamics by digital growth of diluted magnetic semiconductor CdMnTe
M. K. Kneip, D. R. Yakovlev, M. Bayer +3
The technological concept of "digital alloying" offered by molecular-beam epitaxy is demonstrated to be a very effective tool for tailoring static and dynamic magnetic properties o…
Perpendicular magnetization reversal, magnetic anisotropy, multi-step spin switching, and domain nucleation and expansion in Ga1-xMnxAs films
X. Liu, W. L. Lim, L. V. Titova +4
We present a comprehensive study of the reversal process of perpendicular magnetization in thin layers of the ferromagnetic semiconductor Ga1-xMnxAs. For this investigation we have…
Zero- and one-dimensional magnetic traps for quasi-particles
P. Redlinski, T. Wojtowicz, T. G. Rappoport +3
We investigate the possibility of trapping quasi-particles possessing spin degree of freedom in hybrid structures. The hybrid system we are considering here is composed of a semi-m…
