The surface topography of epitaxial MnAs films on GaAs(001) is studied by scanning probe microscopy. We provide direct experimental evidence for temperature-dependent elastic domains the coexisting ferromagnetic αMnAs and paramagnetic βMnAs phases. results agree well with a theoretical model equilibrium periodic domains.
