The absolute thermoelectric power S of amorphous metallic alloys (Fe1-xCrx)84B16 has been measured as a function of temperature in the range of 80 to 380 K for 0.01≤x≤0.46. It is found that the behavior of S(T) for the magnetic alloys does not always follow a nonlinear variation law with a shallow minimum. The. addition of a small amount of Cr (x≤0.05) is shown to lower the absolute value of S and wash out the minimum. With a larger Cr content, the alloys are weakly magnetic and the behavior of S(T) changes from nonlinear, typical of magnetic amorphous alloys, to nearly linear, similar to that for nonmagnetic alloys. A value of x of 0.15 and 0.25 is not found to have any effect on the value of 8 at the Curie temperature Tc, which happened to he in our working temperature region.
