J. Deboeck et al., CONTROLLED FORMATION OF NANOSCALE MNAS MAGNETIC CLUSTERS IN GAAS, Journal of magnetism and magnetic materials, 156(1-3), 1996, pp. 148-150
Nanocrystalline MnAs magnetic clusters are formed controllably in GaAs
by annealing Molecular Beam Epitaxial grown Ga1-xMnxAs (0.03 < x < 0.
15). Magnetic and structural properties (cluster size, epitaxial regis
try) are addressed. The semiconductor matrix is defect free, and excel
lent control in cluster location is demonstrated. Semiconductor layers
grown on top of a heterogeneous GaAs/MnAs clustered buffer show good
optical properties.
