Magnetic scattering of spin polarized carriers in (In,Mn)Sb dilute magnetic semiconductor
M. Csontos, T. Wojtowicz, X. Liu +3
Magnetoresistance measurements on the magnetic semiconductor (In,Mn)Sb suggest that magnetic scattering in this material is dominated by isolated Mn ions located outside the…
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…
Definitive observation of the dark triplet ground state of charged excitons in high magnetic fields
G. V. Astakhov, D. R. Yakovlev, V. V. Rudenkov +8
The ground state of negatively charged excitons (trions) in high magnetic fields is shown to be a dark triplet state, confirming long-standing theoretical predictions. Photolumines…
Andreev Reflection and Pair Breaking Effects at the Superconductor/Magnetic Semiconductor Interface
R. P. Panguluri, K. C. Ku, T. Wojtowicz +5
We investigate the applicability of spin polarization measurements using Andreev reflection in a point contact geometry in heavily doped dilute magnetic semiconductors, such as (Ga…
