Abstract Ta(x nm)/Ni65Co35 (40 nm) bilayers films (x = 0, 1, 2, 3, 4, 5 nm) have been prepared by DC magnetron sputtering. The effects of the thickness and deposition rate of Ta seed layer on anisotropic magnetoresistance(AMR) and coercivity of Ni65Co35 (40 nm) layer were investigated.XRD and magneto-test showed that a suitable thickness and higher deposition rate of Ta layer could promote the formation of Ni65Co35 layer with (111) texture, and remarkably increase the AMR value of Ni65Co35 layer and the sensitivity of magnetic sensor element.
