Abstract:
An alloy having a formula FeaCobNicCudMeSifBgXh is provided. M is at least one of V, Nb, Ta, Ti, Mo, W, Zr, Cr, Mn and Hf; a, b, c, d, e, f, g are in at. %; X denotes impurities and optional elements P, Ge and C; and a, b, c, d, e, f, g, h satisfy the following: 0≤b≤4,0≤c<4,0.5≤d≤2,2.5≤e≤3.5,14.5≤f≤16,6≤g≤7,h<0.5, and1≤(b+c)≤4.5,     The alloy has a nanocrystalline microstructure, a saturation magnetostriction of |λs|≤1 ppm, a hysteresis loop with a central linear part, and a permeability (μ) of 10,000 to 15,000.
