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…

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…
