Abstract

The domain patterns of ferromagnetic MnAs wires on GaAs(001) were investigated by atomic force microscopy (AFM), magnetic force microscopy (MFM) and SQUID magnetometry. The MnAs films break up into ordered arrays of submicron-sized ferromagnetic α and paramagnetic β wires on GaAs(001) substrates. A variety of complex domain patterns were found in micromagnetic investigations. A strong uniaxial in-plane anisotropy with the easy and hard axis of magnetization being in plane and perpendicular to each other was exhibited by MnAs.
