The anisotropic magnetoresistance and saturation magnetic field of the Permalloy thin films (Ni0.81Fe0.19) sputtered on a nonmagnetic (Ni0.81Fe0.19)0.66Cr0.34 buffer layer were measured. The AMR variations of the films after annealing and the size effect of the AMR stripes after etching were emphatically studied, and a qualitative analysis was proposed through a statistic model. The simulation results agree with the experiments.
