摘要
MnAs grows epitaxially on GaAs(001) through formation of top-flat islands, with sharp sloping sidewalls aligned with the GaAs [1 (1) over bar0] and [110] directions. Magnetization measurements indicate that the easy axis of the MnAs thin films is in-plane, along the [(1) over bar(1) over bar 20] direction. The easy axis is aligned with [110] of GaAs, whatever the first monolayer of Mn was deposited on d(4x4) or (2x1)-Se reconstructed surfaces. (C) 2001 Elsevier Science BY. All rights reserved.
