We examined the effect of the substitution of Fe atoms for Co atoms iron on the thermal and the magnetic properties for (Co1-x Fe (x) )(72)B19.2Si4.8Cr4 (0 a parts per thousand currency sign x a parts per thousand currency sign 1) system. We made ribbons with diameters of 2 mm by using melt spinning technique. The broad X-ray diffraction pattern without any crystalline peaks indicates the fully amorphous structure for all alloys. As the Fe content was increased, the saturation magnetization (M (s) ) increased up to x = 0.9, which indicates that an iron/cobalt ratio of 9:1 resulted in the maximum saturation magnetization in the (Co1-x Fe (x) )(72)B1(9.2)Si(4.8)Cr(4) (0 a parts per thousand currency sign x a parts per thousand currency sign 1) alloy system.
