Abstract

Chemical composition and surface morphology of Ni-Ga-Fe thin films grown under various sputtering powers and argon gas pressures by r.f. magnetron sputtering technique are studied. X-ray fluorescence results show that the sputtering power has obvious effect on the chemical composition of Ni-Ga-Fe thin films. The argon gas pressure has little effect on the composition of Ni-Ga-Fe thin films. The change in surface morphology of Ni-Ga-Fe films is discussed in terms of root-mean-square (rms) surface roughness values. The grain size and the rms of Ni-Ga-Fe thin films increase with the increase of sputtering power and argon gas pressure. The film deposited at room temperature has a cubic L21 structure and the annealed film shows martensitic structure.
