摘要：

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 of the coexisting ferromagnetic alphaMnAs and paramagnetic betaMnAs phases. The results agree well with a theoretical model for the elastic equilibrium of periodic domains. (C) 2002 American Institute of Physics.
