On the nature of the spin-polarized hole states in a quasi-two-dimensional GaMnAs ferromagnetic layer
E. Dias Cabral, M. A. Boselli, A. T. da Cunha Lima +2
A self-consistent calculation of the density of states and the spectral density function is performed in a two-dimensional spin-polarized hole system based on a multiple-scattering…
Anisotropic spin transport in GaAs quantum wells in the presence of competing Dresselhaus and Rashba spin-orbit-coupling strengths
J. L. Cheng, M. W. Wu, I. C. da Cunha Lima
Aiming at the optimization of the spin diffusion length in (001) GaAs quantum wells, we explore the effect of the anisotropy of the spin-orbit coupling on the competition between t…
Spin relaxation time, spin dephasing time and ensemble spin dephasing time in -type GaAs quantum wells
C. Lü, J. L. Cheng, M. W. Wu +1
We investigate the spin relaxation and spin dephasing of -type GaAs quantum wells. We obtain the spin relaxation time , the spin dephasing time and the ensemble spin…
Charge and spin distributions in GaMnAs/GaAs Ferromagnetic Multilayers
S. C. P. Rodrigues, L. M. R. Scolfaro, J. R. Leite +3
A self-consistent electronic structure calculation based on the Luttinger-Kohn model is performed on GaMnAs/GaAs multilayers. The Diluted Magnetic Semiconductor layers are assumed…
Indirect exchange in GaMnAs bilayers via spin-polarized inhomogeneous hole gas: Monte Carlo simulation
M. A. Boselli, I. C. da Cunha Lima, A. Ghazali
The magnetic order resulting from an indirect exchange between magnetic moments provided by spin-polarized hole gas in the metallic phase of a GaMnAs double layer structure is stud…
Magnetic interaction between GaMnAs layers via spin-polarized quasi-two-dimensional hole gas: Monte Carlo simulation
A. Boselli, L. Loureiro da Silva, I. C. da Cunha Lima +1
The magnetic order resulting from an indirect exchange between magnetic moments in the metallic phase of a Ga(1-x)Mn(x)As bilayered structure is studied "via" Monte Carlo simulatio…
