It is obtain-ed that the average magnetic moment, μ, per magnetic atom and Curie temperature,T_c, in the amorphous FeSiZr alloys increase with increasing Si content. The μ andT_c are found to be quite small, compared with amorphous FeSiB alloys. This unu-sual behaviour is suggested to be due to the presence of the Fe-Fe antiferromagneticinteractions. The temperature dependence of magnetization at low temperature is inaccordance with Bloch T~(3/2) law. Calculation shows that the spin wave stiffnessconstant, D, increases with increasing Si conteat from 0.37 meV·nm~2 for x=0 to0.538 meV·nm~2 for x=10. The values of 〈r~2〉 indicate that the range of the exchangeinteraction is roughly the mean atomic distance of nearest neighbours.
