Abstract

A anomalous Hall heat current and the Nernst effect in the CuCr ₂Se_4-xBr_x ferromagnet was analyzed. The variation of α_xy with the hole density and lifetime τ in the ferromagnet was also measured. It was found that α_xy is independent of τ at low temperatures, consistent with the anomalous-velocity theories. It was observed that fluctuations of the paramagnetic magnetization lead to a significant transverse electrical current that is proportional to the average magnetization.
