| Research Abstract |
The phase transition whose order parameter can be considered as 'chirality' has been investigated by using anomalous Hall effect on canonical spin glass systems. The Dzyalosinsky-Moriya anisotropy was controlled by changing the atomic radius of the host metall. The results strongly suggests that the existence of the phase transition characterized by chirality.
