PAC investigation of qudropole interaction in nano-soft magnetic material Fe73.5Cu1Nb3Si13.5B9

摘要

The quadrupole interaction in nano-soft magnetic material Fe73.5Cu1Nb3Si13.5B9 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.
