Purpose<\/strong>. The study aims to develop and characterize a new nanostructured FeCo0,854<\/sub>Nb0,146<\/sub>NiB0,7<\/sub>Si0,3\u00a0<\/sub>high-entropy metallic glass with enhanced soft magnetic and mechanical properties. The research seeks to explore the interplay between the alloy\u2019s amorphous structure and its functional properties to advance the understanding of high-entropy metallic glasses.\u00a0Design \/ Method \/ Approach<\/strong>. The amorphous films of the FeCo0,854<\/sub>Nb0,146<\/sub>NiB0,7<\/sub>Si0,3\u00a0<\/sub>alloy was synthesized using splat-quenching technique. The cooling rate, estimated based on the film thickness, was ~106<\/sup>\u00a0K\/s. Structural properties were analyzed via X-ray diffraction (XRD), differential thermal analysis (DTA), and electrical resistivity measurements. Magnetic properties were assessed using a B\u2013H curve tracer and vibrating sample magnetometer, while microhardness was measured with a PMT-3 tester.\u00a0Findings<\/strong>. The alloy exhibits a fully glassy structure with a crystallite size of ~3 nm, low coercivity (40 A\/m), high saturation magnetization (74 A\u00b7m2<\/sup>\/kg), and microhardness \u2265 8000 MPa, indicating decent soft magnetic and mechanical properties.\u00a0Theoretical Implications<\/strong>. The research provides significant insights into the role of atomic-size differences, configurational entropy, and thermodynamic parameters in stabilizing the glassy phase in high-entropy alloys. It advances the theoretical framework for designing high-entropy amorphous materials.\u00a0Practical Implications<\/strong>. The characteristics of the material make it promising for use in electronic devices and mechanical engineering parts.\u00a0Originality \/ Value<\/strong>. This study provides a comprehensive analysis of the high-entropy metallic glass FeCo0,854<\/sub>Nb0,146<\/sub>NiB0,7<\/sub>Si0,3<\/sub>, offering new insights of its magnetic and mechanical properties through advanced characterization techniques.\u00a0Research Limitations \/ Future Research<\/strong>. Further studies are needed to investigate the long-term stability of the fabricated amorphous alloy.\u00a0Article Type<\/strong>. Applied Research.<\/p>\n\n\n\n
