The role of resident electrons in manifestation of a spin polarization memory effect in Mn delta-doped GaAs heterostructures
Mikhail Dorokhin, Mikhail Ved, Polina Demina +6
The spin-memory effect in the GaAs / InGaAs heterostructures with <Mn> layer in GaAs barrier have been investigated. The effect consists in spin polarization of Mn atoms due to…
High-temperature intrinsic ferromagnetism in heavily Fe-doped GaAs layers
A. V. Kudrin, V. P. Lesnikov, Yu. A. Danilov +10
The layers of a high-temperature novel GaAs:Fe diluted magnetic semiconductor (DMS) with an average Fe content up to 20 at. % were grown on (001) i-GaAs substrates using a pulsed l…
Robustness of ferromagnetism in (In,Fe)Sb diluted magnetic semiconductor to variation of charge carrier concentration and Fermi level position
A. V. Kudrin, V. P. Lesnikov, Yu. A. Danilov +11
The influence of He+ ion irradiation on the transport and magnetic properties of epitaxial layers of a diluted magnetic semiconductor (DMS) (In,Fe)Sb, a two-phase (In,Fe)Sb composi…
Acceleration of the precession frequency for optically-oriented electron spins in ferromagnetic/semiconductor hybrids
F. C. D. Moraes, S. Ullah, M. G. A. Balanta +6
Time-resolved Kerr rotation measurements were performed in InGaAs/GaAs quantum wells nearby a doped Mn delta layer. Our magneto-optical results show a typical time evolution of the…
The formation of epitaxial p-i-n structures on the basis of (In,Fe)Sb and (Ga,Fe)Sb layers
A. V. Kudrin, V. P. Lesnikov, D. A. Pavlov +8
Multilayer structures on the basis of n-type (In,Fe)Sb and p-type (Ga,Fe)Sb diluted magnetic semiconductors (DMS) along with separate (In,Fe)Sb and (Ga,Fe)Sb layers were fabricated…
Magnetic properties, chemical and phase composition of thin manganese silicide films fabricated by pulsed laser deposition
M. V. Dorokhin, Yu. M. Kuznetsov, V. P. Lesnikov +8
Manganese silicide (MnxSiy) thin films with Mn content (CMn) varied from 24 at. % to 52 at. % were grown on i-GaAs (100) substrates. Chemical, phase composition and room temperatur…
