| Chiral susceptibility in canonical spin glass and reentrant alloys from Hall effect measurements (2003) | |||||||||
Abstract | |||||||||
| The extraordinary Hall effect coefficients $R_s(T)$ of the canonical spin glass alloys ${\bf Au}Fe 8 at%$ and ${\bf Au}Mn 8 at%$ and of an archetype reentrant system ${\bf Au}Fe 18 at%$ were measured as functions of temperature. The data show a critical cusp-like term superimposed on a smooth background for the spin glasses, and change of sign with temperature for the reentrant. The results can be interpreted consistently by invoking a chiral Hall effect contribution as proposed by Kawamura. | |||||||||
