| description | In this work, the thermal behavior, soft magnetic properties, and structure of Fe<sub>86−x</sub>P<sub>11</sub>C<sub>2</sub>B<sub>1</sub>W<sub>x</sub> (x = 0, 0.1, 0.2, 0.4, 0.6, 0.8, 1, 2, and 4) amorphous alloys were researched by several experimental methods and ab initio molecular dynamics. The addition of W improved the thermal stability of the alloy system when the first onset crystallization temperature (<i>T</i><sub>x1</sub>) increased from 655 K to 711 K, significantly reduced the coercivity <i>H</i><sub>c,</sub> and decreased the saturation magnetization <i>B</i><sub>s</sub>. The Fe<sub>85.6</sub>P<sub>11</sub>C<sub>2</sub>B<sub>1</sub>W<sub>0.4</sub> alloy showed optimal soft magnetic performance, with low <i>H</i><sub>c</sub> of 1.4 A/m and relatively good <i>B</i><sub>s</sub> of 1.52 T. The simulation results suggested that W atoms increased the distance of the neighboring Fe-Fe pair, reduced the coordination number, narrowed the gap between the spin-up and spin-down electrons of each atom, and decreased the average magnetic moment of the Fe atoms. This work demonstrates a micro-alloying strategy to greatly reduce <i>H</i><sub>c</sub> while maintaining high <i>B</i><sub>s</sub>. |
