Reduction of Threshold Current for Domain Wall Depinning Using Gd Doping of Permalloy

The dependence of threshold current on applied magnetic field for domain wall depinning from a pinning potential in Gd doped permalloy wires is measured using pulsed current measurements. By increasing the Gd concentration we find a marked reduction in threshold currents. This is shown to arise due...
