摘要：
The point contact Andreev reflection technique was employed to estimate the spin polarization of currents in Co/Pt multilayered thin film and Co-Pt alloy film with perpendicular anisotropy. The spin polarization of currents in the Co-Pt alloy film was estimated to be 0.48, while that in Co/Pt multilayered film was 0.56. These results suggest that the spin-polarization of currents in multilayered film is enhanced compared to that in alloy film. (C) 2010 American Institute of Physics. [doi: 10.1063/1.3460910]
