Investigation of the MgO absorbate and the MgO/Fe on GaAs(001) surface by means of XPS and XPD
We report a combined high-resolution photoemission and photoelectron diraction investigation of a magnesium oxide adsorbate on an Fe surface grown on a GaAs(4x2)-reconstructed substrate. MgO is an appliciable insulator in magnetic tunnel junctions (MTJ) based [...]
