Abstract: We investigate the magnetic field dependence of the magnetic and structural phase transition of an epitaxial MnAs layer grown on GaAs (100) by using SQUID magnetometry and X-ray diffraction. The phase transition temperatures obtained from magnetic and structural results revealed an apparent splitting for magnetic field less than ∼1kOe, while for higher magnetic fields a behavior similar to that reported for bulk MnAs is observed. © 2004 Elsevier B.V.
