The Fe(110) electrodes exhibit ∑1↑ and ∑1↓ spin states, both crossing the Fermi level, but with a group velocity about 50% smaller for the minority states compared to the majority ones. These epitaxial but symmetry-mismatched MTJs yield tunneling magnetoresistance (TMR) values of 54% at 1.5 K and 28% at room temperature. The TMR value and the estimated tunneling spin polarization are consistent with a partial spin filtering due to the ∑1↑ states partially compensated by the ∑1↓ states.</dcterms:abstract> </rdf:Description> </rdf:RDF>
