| Structural relaxation of amorphous Fe40Ni40B20 alloy has been studied by the method of angular correlation of positron annihilation. Inexpressive changes of the spectra after the annealing for 2 x 103 min at 473 K suggest some changes in topological order. The relatively low sensitivity of positron annihilation to the structural relaxation of the amorphous alloy is probably caused by the high density of vacancy-like defects in the alloy. |
