Three series of Fe-Ni-Si, Fe-Ni-Nb and Fe-Ni-Nb-Mo alloys were studied. Ni86Si2Mo2Fe alloy in Fe-Ni-Si series was annealed at 1150 ℃ for 3hr. After cooling at 580 ℃ for 2h, μ_o = 23100Gs / Oe, μ_m = 23400Gs / Oe and Hc = 0.023Oe Br = 870Gs after annealing at 580 ℃ for 2hr. The Nb content in Fe-Ni-Nb alloy was annealed at 1250 ℃ for 3hr at 9.73% And cooled to 100 ° C / hr to obtain μo = 64000Gs / Oe, μ_m = 450000Ge / Oe, Hc = 0.0048Oe, p = 79.3βΩ-cm and Hv> 200. Ni78Mo2 in the Fe-Ni-Nb-Mo based alloy .5Nb9Fe after annealing at 1150 ° C for 3hr and cooling at 100 ° C / hr, μ_o = 3300Gs / Oe, μ_m = 126500Gs / Oe, Hc = 0.011 Oe, Hv = 243 and p = 90μΩ ~ cm were obtained.
