Magnetic properties are studied within the thin Co88Cr12/Cr films sputtered either with pure argon gas or with a helium-argon (10:3) gas mixture. Through comparison of coercivities, coercive squarenesses, ΔM(H) and SFDdc plots of these films, the effects of variable underlayer and magnetic layer thickness are studied. There is a strong correlation between magnetic interactions in films and sputter gas types. These results indicate the crystal texture of the films sputtered in different types of gas is different. With XRD measurement, the crystal orientation ratio in the films sputtered in pure argon is different from that in the gas mixture. AFM images prove that the thin films sputtered in the mixture have smaller grain sizes than those sputtered in pure argon.
