Magnetic ordering of Mn overlayers on GaAs(100).
نویسندگان
چکیده
Growth of Mn on GaAs(100) is studied by photoemission and electron-energy-loss spectroscopy. %e find that the first layer of Mn grows on GaAs(100) in a two-dimensional mode, where about 10% of the Mn atoms take part in the chemical reaction with the substrate. The electronic structure of the ultrathin film of Mn is found to be very different from that of bulk a-Mn, and the possibility that magnetic ordering exists in the ultrathin overlayer of Mn is proposed.

of 3d transition metals (Sc, Ti, Cr, Mn , Fe, Co, Ni) in both far and close situations were studied based on spin polarised density functional theory using the generalized gradient approximation (LDA) with SIESTA code. The electronic structures show that zigzag (0,9) GaAs nanotubes are non-magnetic semiconductors with direct band gap. It was revealed that doping of 11.11 % Fe and Mn concentrati...
متن کاملMixed magnetic phases in (Ga,Mn)As epilayers.
Two different ferromagnetic-paramagnetic transitions are detected in (Ga,Mn)As/GaAs(001) epilayers from ac susceptibility measurements: transition at a higher temperature results from (Ga,Mn)As cluster phases with [110] uniaxial anisotropy and that at a lower temperature is associated with a ferromagnetic (Ga,Mn)As matrix with 100 cubic anisotropy. A change in the magnetic easy axis from [100] ...
متن کاملAb-initio study of exchange constants and electronic structure in diluted magnetic group-IV semiconductors
Exchange-constants have been evaluated from first-principles in Mn-doped Ge, mainly focusing on the effects of the impurity concentration and of the arrangement of Mn-atoms in the semiconducting matrix. As expected, the Mn-concentration strongly affects the magnitude of the exchange constants (especially between Mn as first-nearest-neighbors (NNs) in the cation position). Interestingly, the arr...
متن کاملQuantum, normal and anomalous Hall effect in 2D ferromagnetic structures: GaAs/InGaAs/GaAs quantum well with remote Mn delta-layer
We study experimentally the electronic transport and magnetism of GaAs/InGaAs/GaAs quantum wells (QW) with remote Mn -layer. The 2D energy spectrum of the carriers is revealed by quantum Hall Effect measurements. The ferromagnetic ordering is evidenced by anomalous Hall Effect and direct magnetization measurements. A signature of this state is also observed on the temperature dependence of the ...

A model potential for GaAs~100! and InAs~100! surface atoms is developed and surface reconstructions on GaAs~100! and InAs~100! are studied with the conjugate gradient ~CG! method. Not only does this model reproduce well surface energies for the ~100! orientation, it also yields (132) dimer lengths in accordance with ab initio calculations. Large-scale molecular dynamics ~MD! simulations are pe...
