/sup 57/Fe Moessbauer spectroscopy under external magnetic fields of up to 72 kOe has been used to study the magnetic ordering in amorphous (Fe/sub x/Mn/sub 1-x/)/sub 75/P/sub 16/B/sub 6/Al/sub 3/ (0.25< or =x< or =1) at 4.2 K. From the behavior of the magnetic hyperfine fields one concludes that the Fe-rich samples are soft ferromagnets and the Mn-rich samples exhibit spin glass-like properties. In the samples with intermediate Fe concentrations, a magnetic ordering where both ferromagnetic and spin glass-like orderings coexist occurs.
