摘要: Abstract Magnetic and structural properties of Fe films grown on MgO buffered GaAs(001) substrates were investigated. Structural analysis using a transmission electron microscope shows that the Fe/MgO/GaAs system is fully epitaxial when at high temperature (~350 °C). A two-fold uniaxial magnetic anisotropy along Fe[100]//GaAs[110] was found for hysteresis loop measurements domain imaging. However room deposited amorphous island morphology with discrete boundary, no found.
