The dependence of the magnetoresistance ratio, ΔR/Rs, on the Ni content has been studied in Fe/Al2O3/Ni1-xFex (0≤x≤1) tunneling junctions. The value of ΔR/Rs at 4.2 K increased with increasing x and exhibited a maximum of ∼35% at x=0.8. The result is discussed by taking into account the spin-polarization of ferromagnetic electrodes.
