We report on two experiments. In the first one, the stripe phase of perpendicularly magnetized ultrathin films is shown to form a Mermin-like 2D solid with algebraic correlations. The second one consists in exciting the spin motion in a vortex-like spin configuration by an ultrashort magnetic field pulse and imaging the local spin dynamics with pico-second time resolution. Both experiments reveal new non-linear aspects of ultrathin film magnetism.
