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 spinsystems. In double exchange (DE) ferromagnets, the conduction electrons arestrongly coupled with core spins through Hund's rule, and in the presence ofnon-trivial spin texture, acquire a Berry phase contribution to the anomalousHall effect (AHE). We combine Hall and magnetization data on CrO$_2$ with athermodynamical scaling hypothesis to confirm that the critical behavior of thetopological-spin-defect density is consistent with that of the heat capacity.This analysis is the first experimental confirmation of the topologicalcharacter of critical fluctuations.Comment: 4 Figure
