N2 - Nanostructured ferromagnets provide a variety of well-defined magnetization configurations. The symmetry of these configurations in a ferromagnetic nanostructured ring can be altered by an external magnetic field in a controllable manner. We found, by means of resistive-noise spectroscopy, that the chiral-symmetry breakdown of a micromagnetic configuration accompanies a critical fluctuation of the magnetization distribution analogous to a second-order phase transition.
