The thickness dependence of the in-plane uniaxial anisotropy and coercive field of epitaxial MnAs thin films on GaAs (0 0 1) substrates has been determined from the magneto-optic Kerr effect. The metalorganic vapor phase epitaxy grown films are single a phase at room temperature with a B-type varian
We have investigated the initial growth mechanism of MnAs on GaAs(0 0 1)-c(4 ร 4)a reconstructed surfaces. We found that the MnAs deposition on GaAs(0 0 1)-c(4 ร 4)a surface promotes to break the Ga-As asymmetric dimers and modulates the dimer characteristics to symmetric As-As dimer formation on th
