A series of amorphous Fe/sub 80-//sub x/M/sub x/B/sub 14/Si/sub 6/ (M = Mn, V, Cr, and x = 2, 4, 6, 8, 10, 12, and 14 at. %) alloys have been made by the spinning-wheel method. We have measured the density delta, saturation magnetization M/sub s/ , electrical resistivity rho/sub 0/, Hall resistivity rho/sub H/, and magnetoresistance ..delta..rho/rho/sub 0/ of each sample at room temperature. The anomalous Hall coefficient R/sub s/ is determined from the relation rho/sub H/ = R/sub 0/B+R/sub s/M/sub s/. R/sub s/ is found to vary as R/sub s/ = Arho/sup 1.7//sub 0/. The density, magnetization, and magnetoresistance are all decreasing functions of x. The Curie temperature T/sub C/ is determined from the low-field thermomagnetization data and the Arrott plot. The positive forced magnetoresistivities are discussed from the viewpoint of the current models.
