Figure 16

Optical microscopy images of CNC films observed in reflection through a filter selecting left-circularly polarized light (the brightness was enhanced for gray scale printing purposes). a) polydomain film displaying disordered stripy patterns with various periodicities Δ ranging from 0.85 – 2 μm [H = 0, cf. Fig. 14(a)]. b) monodomain film made under a tilted magnetic field, displaying uniform stripy patterns with regular periodicities Δ ≈ 2 μm, (μ 0 H ≈ 0.5 T, βH ≈ 50°, cf. Fig. 14c). c) monodomain film made under vertical field, displaying uniform color with a diverging Δ [μ 0 H ≈ 0.5 T, βH ≈ 0°, cf. Fig. 14(b)].
