Abstract

Sputter deposited Fe-Ti films with small modulation wavelengths in a wide composition range were examined by X-ray diffraction. Mössbauer spectroscopy and differential scanning calorimetry. Complete interdiffusion occurs in case of 15 Å iron and 5.6 to 88.9 Å titanium layer ticknesses and metastable phases are formed which are crystalline at large titanium or iron concentrations and amorphous at intermediate concentrations. Mössbauer spectroscopy gives evidence that the phase around equiatomic concentrations is not microcrystalline, but it is similar to the amorphous phase prepared by the usual method of sputtering. Superlattice reflexions in the X-ray diffractograms indicate that the layer structure is maintained, probably by concentration differences along the growth direction.
