Abstract
Metastable phase formation and magnetic properties of the Fe50(HfxTa1−x)50 (x=0, 0.2, …, and 1) thin films induced by ion beam mixing are studied. The results show that unique amorphous phases could be formed in all the six multilayered films. Interestingly, preferred orientations and formation of BCC-Hf phase were observed in the Fe50Hf50 multilayered films at as-deposited state and after irradiated to doses less than 6×1014Xe+/cm2. In addition, good soft magnetic properties were obtained in the formed amorphous phases. The Fe50Hf40Ta10 amorphous phase owns the maximum magnetization of 45emu/g (i.e., 1.21μB per Fe atom) at 5K, with a saturate magnetization of 7.5emu/g and a small coercivity Hc=7Oe at room temperature. The possible mechanisms responsible for the observations are discussed in terms of atomic collision theory and crystallography.
