Fig. 3: Field history effects on transport properties of the Fe/Gd patterned wire.

a, b Field-dependent polar longitudinal resistivity (\({\rho }_{{xx}}^{\odot}\)) of the 10μm-wide Fe/Gd patterned wire at a T = 300 K and b T = 160 K under two consecutive field history protocols. The inserts in a, b show the H_z field sweep protocols for the four field-dependent \({\rho }_{{xx}}^{\odot}\) responses (blue, red, green, black-colored datasets) that were obtained in sequential order at each temperature: the first sweeps are detailed in a, while the subsequent field sweeps are shown in b.
