A high frequency permeability for an electroplated CoNiFeS film having high saturation magnetic flux density(Bs) of 1.7T and high resistivity(ρ) of 51μΩ-cm was investigated in comparing with CoNiFe film having ρ=25μΩ-cm value. Both films had suitable thermal stability on magnetic properties up to 300°C and magnetic anisotropy(Hk) could be controlled by annealing with magnetic field. Higher permeability of the CoNiFeS film could be attributed to decrease the eddy current loss based on twice higher resistivity compared with the CoNiFe film.
