Effects of neutron irradiation on Fe{sub 30}Ni{sub 48{minus}{ital x}}Cr{sub {ital x}}Mo{sub 2}Si{sub 5}B{sub 15} glassy ribbons are studied by transmission {sup 57}Fe Moessbauer spectroscopy. The spectra are fitted using NORMOS DIST programs accounting for line asymmetries. Bimodal {ital P}({ital H}) distributions are obtained, and they are presented in the form of three-dimensional graphs, the second dimension in these projections being built from Cr content and neutron fluence, respectively. A neutron-irradiation-induced ferromagnetic-to-paramagnetic transition is observed. Changes in the hyperfine parameters are supposed to be governed by a rearrangement of the constituent atoms, including clustering of Cr and by stress centers because of irradiation.
