Magnetic properties of the Fe48.75 Pt 26.25 B 25 nanostructured alloy
Abstract
<p>The Fe48.75Pt26.25B<sub>25</sub>powder was prepared by high-energy ball milling of the crystalline melt-spun ribbon. The X-ray diffraction and transmission Mössbauer spectroscopy measurements allowed the identification of the tetragonal FePt and orthorhombic FeB phases in the as-quenched alloy. The ball milling of the ribbon led to the transformation of the ordered tetragonal FePt phase into a disordered cubic FePt solid solution with the average crystallites size of about 15 nm. Annealing of the as-milled powder recovered the nanocrystalline tetragonal FePt phase. Differences in magnetic properties between the as-milled and annealed powders were revealed by hysteresis loop and magnetization vs. temperature measurements. © 2009 IOP Publishing Ltd.</p>
