Magnetic and structural properties of MnAs thin films on GaAs(111)B: Influence of the growth temperature

The magnetic and structural properties of MnAs thin films grown on GaAs(111)B at different temperatures (160–280°C) are investigated. A narrow optimum growth temperature window (200–240°C) is found where the Curie temperature and the room temperature magnetization are maximized. High-resolution x-ray diffraction experiments are performed on the samples showing that the films are epitaxial for a minimum growth temperature of 200°C. The room temperature fraction of the hexagonal phase is strongly dependent on the growth temperature in agreement with the magnetic properties.
