 note = {We investigated the effect of Ag doping on atomic order and spin polarization of Co2FeSi Heusler alloy thin films. The Co2FeSi film doped with 3at.%-Ag showed improved degree of B2- and 〖L2〗_1-ordering after thermal annealing comparing to Co2FeSi film. Negative sign of anisotropic magnetoresistance suggests the half-metallic nature of Ag-doped Co2FeSi film after annealing at a relatively low temperature of 300 °C. The current-perpendicular-to-plane pseudo spin-valves using the Ag-doped Co2FeSi ferromagnetic (FM) electrodes showed about 1.2 times larger MR ratio than that using the Co2FeSi FM electrodes, reflecting an enhanced spin polarization in Ag-doped Co2FeSi film. Micro-structure analysis revealed the doped Ag was rejected out of Co2FeSi layer after annealing. This study suggests Ag doping to Co-based Heusler compound having no/few solubility with Ag is beneficial for realizing spin-valves with high output at moderate annealing conditions.},
