摘要：

The anomalous Hall coefficient R-s has been studied for the reentrant spin glass system Fe0.7Al0.3 by measuring the magnetization M and the Hall resistivity rho(H). We have found that R-s exhibits anomalous change of the temperature dependence at the spin-glass transition temperature T-G, indicating that an additional term appears along with the beginning of the spin glass phase. The result is discussed in relation to the recent proposal of the chirality mechanism of the Hall effect in the spin glass phase.
