The orientation dependence of current-perpendicular-to-plane giant-magnetoresistance (CPP-GMR) was investigated by fabricating 001 textured polycrystalline pseudo spin valves (PSVs) with Co2Fe(Ga 0.5Ge0.5) (CFGG) Heusler alloy ferromagnetic layers and a Ag spacer. The PSV with 10 nm CFGG annealed at 400°C exhibited the resistance-change area product (ΔRA) of 5.8 mΩ (MR ratio of 16%), the largest value reported for polycrystalline CPP-(P)SVs. The 001 textured CFGG PSV outperforms the 011 textured CFGG PSV possibly due to the reduced lattice mismatch or improved band matching at the CFGG/Ag interface.
