Impact of Gd dopants on current polarization and the resulting effect on spin transfer velocity in Permalloy wires
Abstract
<jats:p>A spin wave Doppler technique is used to measure the spin transfer velocity and the current polarization in current-carrying (Ni0.80Fe0.20)1−xGdx alloy wires. Reduced magnetization values with Gd doping suggest possible increases in the spin transfer velocity. Contrary to these expectations, we measured a decrease in the spin transfer velocity upon introducing Gd dopants. For a current density of 1011 A/m2, the measured velocities range from 6.0 m/s ± 0.6 m/s for pure Permalloy (Ni0.80Fe0.20) to 2.6 m/s ± 0.3 m/s for (Ni0.80Fe0.20)0.945Gd0.055. Interpretation of these values yields a current polarization ranging from 0.71 ± 0.02 to 0.30 ± 0.01 for the same compositions. These results reveal that Gd dopants in Permalloy have a more significant impact on the current polarization than on the material’s magnetization for these alloy compositions.</jats:p>
