Abstract The ribbon samples of Fe-base amorphous alloys Fe_(80)B_(20)(A),Fe_(77.84)B_(16.81)Si_(3.49)C_(1.86)(B),Fe_(65.66)Co_(17.3)B_(15.84)Si_(1.2)(C)and Fe_(65.92)Co_(17)B_(13.29)Si_(1.59)C_(1.1)P_(1.1)(D)wereprepared by melt spinning.Their saturation magnetization at 12 KOe was deter-mined by extracting sample magnetometer and magnetic balance in the tempera-ture range of 1.5—300 K or 300—1200K respectively.It was obtained that themean magnetic moment per atom of transition metal,μ,is(2.03—2.07)μ_R forall samples.Both alloys A and B have similar room temperature saturation mag-netization,σ_S(R.T.),and Curie temperature,T_C,but alloys C and D are higherabout 6% and 10% than those of A respectively.As the experimental results ofthe thermomagnetization,resistivity,DSC and X-ray diffraction,the crystallinephases were also analyzed.The crystallization temperature,T_(cr),of alloys C andD is similar to that of alloy A,and T_(cr)of alloy B is higher about 80 K thanthat of A.The effect of chemical bond,T_(cr)vs e/a and the complexity crystal-line phases on the stability of the Fe-base amorphous alloys has been discussed.
