To study what roles spin structures of ferromagnets play in determining their Hall resistivity ρH or to see if the spin chiral order really contributes to the unusual behavior of anomalous Hall resistivity, we have carried out transport and neutron diffraction studies on the spinel-type system Cu1-xZnxCr2Se4, which is a collinear ferromagnet at x ∼ 0 and in the helimagnetic state at x = 1.0. It is established that the sign change of ρH takes place, with decreasing temperature, along with the appearance of the conical spin structure in the region 0<x<1.0.
