As in such 2D systems as the XY model, topological (or singularity point) defects are thought to play a crucial role in the phase transitions of 3D spin systems. In double exchange (DE) ferromagnets, the conduction electrons are strongly coupled with core spins through Hund's rule, and in the presence of non-trivial spin texture, acquire a Berry phase contribution to the anomalous Hall effect (AHE). We combine Hall and magnetization data on CrO$_2$ with a thermodynamical scaling hypothesis to confirm that the critical behavior of the topological-spin-defect density is consistent with that of the heat capacity. This analysis is the first experimental confirmation of the topological character of critical fluctuations.
