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

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.
