Calculated distribution of the IFE effective magnetic field in the experimentally studied MPMC (a,b) and in the MPMC with three times thicker layers (c). (a) The IFE magnetic field in the magnetic film of the experimentally studied MPMC at the cavity resonance (black curve) and in the same single magnetic film on the substrate (blue curve) at λ = 642 nm. (b) The IFE magnetic field in the magnetic film of the experimentally studied MPMC at λ = 642 nm (black curve), 800 nm (blue curve), and 808 nm (red curve). In (a) and (b) two magnetic layers are shown: the main one (M1, 0 < z < 210 nm) and the auxiliary one (M2, 210 < z < 282 nm). (c) The IFE magnetic field enhancement factor, K, in the MPMC with the main resonance at λ = 1841 nm as compared to the single magnetic film at the 1-st order (λ = 1841 nm, blue curve) and 2-nd order (λ = 647 nm, black curve) cavity resonances. The MPMC in (c) has Bragg mirrors of four pairs of 228-nm-thick TiO2 and 351-nm-thick SiO2 layers, and the magnetic film of 410-nm-thick Bi1.5Gd1.5Fe4.5Al0.5O12. Area of the magnetic layer is shown (0 < z < 410 nm). Inset: transmission spectrum of the MPMC with the main resonance at λ = 1841 nm.
