Abstract：
The quadrupole interaction in nano-soft magnetic material Fe_73.5Cu₁Nb₃Si_13.5B₉ has been studied by perturbed angular correlation using ⁶²Zn probe nuclei from the ISOL radioactive nuclear beam facility at CIAE HI-13 tandem accelerator. Two quadrupole interaction frequencies ω₀₁=440 Mrad/s with a distribution width σ=0 and ω₀₂=90 Mrad/s with a width σ=0.48 are obtained. The fractions of ω₀₁ and ω₀₂ are 38% and 62%, respectively. The measured quadruple interaction parameters indicate that 62% of the implanted ⁶²Zn are located in the grain boundary and 32% in the grain.
