| Abstract | ||||
| Magnetization processes were investigated at room temperature as function of applied tensile stress for the amorphous alloy of nominal composition Fe40Ni38B18Mo4. The alloy had soft magnetic property with positive magnetostriction character. The average saturation magnetization (0.55 T) is almost independent of applied stress. Susceptibility at maximum magnetization, initial susceptibility and Rayleigh constant for different applied stresses were evaluated. Analysis of the magnetization process at high fields shows monotonic decrease of the anisotropy energy with increase of applied stress. The saturation magnetostriction constant is 9.10 x 10-6. The amorphous ferromagnetic alloy is suitable candidate for magnetostrictive sensors fabrication. | ||||
