Low field magnetic properties of amorphous (Fe_{x}Co_{1})_{76}Mo_{8}Cu_{1}B_{15} alloys (x=3, 6 and 9) were characterized by magnetic after-effect and initial magnetic susceptibility. Activation energies and pre-exponential factors of the Arrhenius law that were derived from the disaccommodation curves are of about 1.188 eV and 10^{-15} s, respectively. Local magnetic arrangement was investigated by ^{57}Fe Mössbauer spectrometry. The average hyperfine magnetic field decreases with increasing Fe/Co ratio due to smaller relative contribution of cobalt. The overall magnetic parameters of the alloy prove its good soft magnetic properties with an application potential.
