MI ratio ΔZ/Z as a function of the external field He for gel at f = ω/2π = 100 MHz and different values of the ferrogel layer thickness d3 (a). MI ratio ΔZ/Z as a function of the external field He for ferrogel at f = 100 MHz and different values of the effective stray field Hp. The parameters of the ferrogel layer are d3 = 1 mm, Hc = 4 Oe and H1 = 750 Oe (b). Parameters used for calculations are l = 1 cm, w = 0.01 cm, 2d0 = 500 nm, d1 = 5 nm, d2 = 100 nm, n = 4, M = 750 G, Ha = 7.5 Oe, ψ= −0.05π, σ1 = 5 × 1017 s−1, σ2 = 4 × 1016 s−1, κ = 0.02 and ε = 70.
