Physical Review B
We report on a thorough experimental investigation of the influence of an FeO layer at the Fe/MgO interface on the magnetotransport properties in epitaxial Fe/MgO/Fe͑001͒ magnetic tunnel junctions. Interfacial oxygen is introduced by adsorbing O 2 on the bottom Fe͑001͒ layer. The morphology and composition of the FeO film are investigated by means of scanning tunneling microscopy, reflection high-energy electron diffraction, and x-ray photoelectrons spectroscopy. We show that the amount ofdoi:10.1103/physrevb.79.224405 fatcat:nyu3k6pstvaitah6jmrkawwwi4
