Abstract

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