Notes:
In order to study the local atomic environments of both B and Fe in Fe3B1−xCx (0.1≤x≤0.4), NMR measurements of the hyperfine field distributions for 10B, 11B, and 57Fe have been performed at 4.2 K and from 10 to 60 MHz. It was found that the 11B and 57Fe NMR frequencies do not change with C concentration. From these results, the 11B NMR frequency characteristic of orthorhombic Fe3B was unambiguously determined to be 36.3 MHz, which is in good agreement with the value obtained for the orthorhombic Fe3B phase prepared by annealing amorphous Fe80B20. Our results show that the substitution of C atoms for B atoms has a small effect on the hyperfine field at both the B and Fe nuclei as well as on the magnetic moment of the Fe atoms.
