 note = {We have measured the spin polarization of half-metallic Heusler alloy Co_{2}MnSi by the Andreev reflection technique. The differential conductance G(V) of Co_{2}MnSi/Pb junctions was measured in the temperature range between 1.5 K and 10 K. The structure of G(V) became gradually smaller with the increase of temperature and disappeared above the superconducting critical temperature T_{c} of Pb thin films. Temperature dependence of the superconducting energy gap Δ(meV) coincides with that of the Bardeen-Cooper-Schrieffer (BCS) theory. The obtained G(V) was able to be fitted very well by the modified Blonder-Tinkham-Klapwijk (BTK) model up to the T_{C}. We have found the spin polarization of 52.5% for Co_{2}MnSi.},
