Abstract

In order to break through the conductive percolation threshold limitation of the conventional granular films to increase resistivity (ρ), while keeping large complex permeability (μ̃), a series of compositionally graded FeCoB-SiO ₂ granular films with different multilayer structures were deposited on flexible substrates. The high-frequency electromagnetic properties were investigated. The experimental results showed that the compositionally graded granular films had obvious in-plane uniaxial magnetic anisotropy and the coercivity in the easy axis (H _ce) was as low as 3.97 Oe. Both the ρ (∼15.4 mΩ·cm) and μ̃ (μ _i′ = 276. 3 and μ″ _max = 441. 4) of the compositionally graded FeCoB-SiO ₂ granular films were simultaneously higher than those of the conventional FeCoB-SiO ₂ granular films. Two resonance peaks of complex permeability spectrum were also observed.
