Research on Soft Magnetic Properties and Hysteresis Loop Linear Control of FeSiBCuNbNi Alloy System

摘要: 通过调节FeSiBCuNbNi合金成分，该合金体系拥有良好的软磁性能并具有一定的恒磁导效果。结果表明：随着B含量的增加，非晶形成能力增强，且提高B的添加量有利于提高合金的热稳定性，同时降低有效磁导率（μ_e），使磁滞回线具有良好的线性效果。B含量为12at%的软磁合金具有高的M_s=165.79 emu/g （B_s=1.52 T）和低的H_c=17.52 A/m，并在0～600 A/m的外加磁场中具有良好的恒磁导率效果，即在该交变磁场中具有良好的抗直流偏置效果。

Abstract: By adjusting FeSiBCuNbNi alloy composition, the alloy system has good soft magnetic properties and a certain constant magnetic permeability effect.The results show that with the increase of B content, the ability of amorphous formation increases, and increasing the amount of B additoin is beneficial to improving the thermal stability of the alloy. At the same time, the effective magnetic permeability (μ_e) reduces, so that the hysteresis loop has a good linear effect. The soft magnetic alloy with B content of 12at% has a high M_s=165.79 emu/g (B_s=1.52 T) and low H_c=17.52 A/m, which has a good constant magnetic permeability effect in an external magnetic field of 0 to 600A/m and a good anti-DC bias effect in the alternating magnetic field.
