Local atomic structure of amorphous Fe81−<i>x</i>Co<i>x</i>Nb7B12 alloys using synchrotron radiation x-ray diffraction and pair-distribution function analysis
Abstract
Fe81−xCoxNb7B12 alloys are members of the high thermal stability and magnetic performance (HITPERM) family of materials, which exhibit exceptional magnetic properties, including high Curie temperatures and magnetic susceptibilities, making them promising for developing materials platforms for high-frequency, high-temperature applications. Here, we combine synchrotron x-ray diffraction measurements with simulations of the pair-distribution function to uncover the local atomic structure of amorphous Fe81−xCoxNb7B12 alloys. By analyzing alloys with varying Fe:Co ratios, we demonstrate how the composition impacts the atomic structure of these alloys. Our study reveals that Fe and Co form clusters near the equiatomic Fe/Co concentration.
