Abstract
<p>Structural and magnetic properties of two rapidly solidified and post-annealed Fe<sub>60</sub>Pt<sub>15</sub>B<sub>25</sub>and Fe<sub>60</sub>Pt<sub>25</sub>B<sub>15</sub>alloys are compared. The as-quenched Fe<sub>60</sub>Pt<sub>15</sub>B<sub>25</sub>ribbon was fully amorphous whereas in the Fe<sub>60</sub>Pt<sub>25</sub>B<sub>15</sub>alloy the amorphous phase coexists with an fcc FePt disordered solid solution. Differential scanning calorimetry curves of both alloys reveal a single exothermal peak with onset temperatures of 873 and 847 K for Fe<sub>60</sub>Pt<sub>15</sub>B<sub>25</sub>and Fe<sub>60</sub>Pt<sub>25</sub>B<sub>15</sub>, respectively. Magnetically hard, tetragonal ordered L1<sub>0</sub>FePt and magnetically soft Fe<sub>2</sub>B nanocrystalline phases were formed due to the annealing of the alloys, as indicated by X-ray diffraction and Mssbauer spectroscopy measurements. Two-phase behavior was detected in the temperature dependence of magnetization of the annealed samples. A magnetic hardening was observed for all annealed ribbons. Magnetic properties of the annealed alloys, studied by hysteresis loop measurements, were related to the differences in the relative fractions of the hard and soft magnetic phases calculated from Mssbauer spectra. The alloy with 25 at% Pt exhibits better hard magnetic properties (H<sub>c</sub>=437 kA/m, M<sub>r</sub>/M<sub>s</sub>=0.74) than the alloy with smaller Pt content (H<sub>c</sub>=270 kA/m, M<sub>r</sub>/M<sub>s</sub>=0.73) mainly due to the larger abundance of the ordered tetragonal FePt phase. © 2010 Elsevier B.V.</p>
