The amorphous Fe_80B_ (20), Fe_ (17.84) B_ (16.81) Si_ (3.49) C_ (1.36), Fe_ (65.66) Co_ (17.3) B_ (15.84) Si_ (1.2) and Fe_ (6) ) Co_ (17) B_ (19.29) Si_ (1.59) C_ ((?). (?)) P_ ((?). (?)) Alloys were prepared by single roll rapid cooling method.The relationship between saturation magnetization and temperature The atomic magnetic moment (?) At 0K was in the range of 2.03-2.07μ B. Amorphous Fe_ (80) B_ (20) and Fe_ (77.84) B_ (16.81) Si_ (3.49) C_ ((? (Σ) (RT) and Curie temperature (Tc) of the alloys at room temperature are similar to those of Co (subscript x) Crystallization transformation was analyzed by thermomagnetic, resistivity, differential thermal analysis and X-ray diffraction.The crystallization temperature T_ (cr) of Co-containing samples was similar to that of Fe_ (80) B_ (20) ) T_ (cr) of B_ (16.81) Si_ (3.49) C_ (1.86) is higher than that of Fe_ (80) B_ (20) about 80 K. The relationship between T_ (cr) and e / α and the complexity of crystallization process The factors affecting the stability of highly saturated amorphous alloys are discussed.
