- The influence of the magnetic field annealing on the magnetoimpedance effect has been investigated in rapidly quenched $(Fe_{0.5}Ni_{0.5})_{78}Nb_{7}B_{15}$ monolayer and bilayer thin ribbons. The highest impedance ratio value $(ΔZ//Z)_{max}$=72% and the maximum field sensitivity $η_{max}$=12 %/Oe was obtained in the bilayer ribbon, annealed under longitudinal magnetic field at 773 K that exhibited nanocrystalline structure. The higher values of $(ΔZ//Z)_{max}$ in bilayer ribbons, as compared to their monolayer counterparts, are attributed to the increased ratio of their thickness to the penetration depth.
