Abstract

The anomalous Hall resistivity ρxy and the magnetization M of a reentrant spin glass Ni(Pt)Mn thin film were simultaneously measured as a function of temperature in fields from 1000 to 9000 Oe. The value of ρxy/M depends on the cooling condition at temperatures below the spin glass transition temperature Tg and the low-field value of ρxy/M shows a cusp like peak around Tg in the zero field cooled (ZFC) condition. The anomaly in the ZFC data can be explained in terms of the contribution to the anomalous Hall effect from chirality mechanism.
