Simulation results of initial magnetization configurations and corresponding spatial distributions of magnetic susceptibility for HDC = +200 Oe (a) and −200 Oe (b). The respective resonance peaks are marked as f1+, f2+, f1−, f2−. Spectral dependences of χ″ for three cases: HDC = 0 Oe (black line), +200 Oe (blue line), −200 Oe (red line) at α = 135° and their superposition (dashed line) are shown in (c).
