Abstract

The extraordinary Hall resistivity ρxy and the magnetization M of a canonical spin glass AuFe were measured simultaneously as a function of temperature with close attention to thermal and magnetic field hysteresis. The data of ρxy show an anomaly at the spin glass transition temperature Tg. Moreover, the value of ρxy/M, which represents the chiral susceptibility of the system in the present case, also shows the anomaly. In conventional theories, the extraordinary Hall resistivity ρxy is represented, ρxy = M(Aρ + Bρ2), where ρ is the resistivity, and A and B are constants. Since ρ (T) is monotonic and smooth, the behavior of ρxy/M clearly indicates that one has to include another term in the expression for ρxy. The results can be interpreted consistently in terms of a chirality ordering model of canonical spin glasses.
