(a) Wide-scan XPS spectra for the intrinsic and Fe (7 at. %) doped MgO thin films and (b) XRD pattern for the same. (c) Room-temperature M(H) hysteretic loops for intrinsic MgO and Fe doped MgO (inset) thin films. Magnetic data have been corrected for the diamagnetic background.
(a) O 1s absorption spectra for Mg1−xFexOy thin films in the excitation range 525–570 eV. (b) X-ray emission spectra representing the occupied DOS of the Mg1−xFexOy thin films.
(a) Band diagram showing the shift in the Ec and Ev as a result of Fe doping. (b) Projected density of states (PDOS) of MgO on O site in Mg32O32 and Mg30O32 super cells, respectively.
Summary of samples under investigation.
