|Title:||The band structure-matched and highly spin-polarized Co2 CrZ/ Cu2 CrAl Heusler alloys interface||Authors:||Ko, V.
|Issue Date:||2009||Citation:||Ko, V., Han, G., Qiu, J., Feng, Y.P. (2009). The band structure-matched and highly spin-polarized Co2 CrZ/ Cu2 CrAl Heusler alloys interface.

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|
