ScholarBank@NUS Repository. https://doi.org/10.1063/1.3263952 | Abstract: | Here we present a lattice- and band-matched nonmagnetic L21 Heusler alloy spacer for Co2 CrZ Heusler alloys where Z=Si or Al. By first principle calculations, we find that the band structure matching is almost perfectly satisfied when they are interfaced with Cu2 CrAl. Despite the loss of half-metallicity due to interface states, our calculations show that the spin polarization at these band-matched (001) interfaces is higher than 80%. These lattice-matched Co2 CrZ/ Cu2 CrAl interfaces with excellent band matching and enhanced spin scattering asymmetry are promising for all-metallic current-perpendicular-to-plane giant magnetoresistance device applications. © 2009 American Institute of Physics. | Source Title: | Applied Physics Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/98246 | ISSN: | 00036951 | DOI: | 10.1063/1.3263952 |
