Abstract

The influence of the Dzyaloshinsky-Moriya (DM) anisotropy on R_s ≡ ρ_ex / M, where ρ_ex is the extraordinary Hall resistivity and M is the magnetization, is investigated in canonical spin glass (SG) alloys. The strength of the DM anisotropy in the alloys is changed systematically by doping the third non-magnetic impurities. The Hall resistivity ρ_H, the magnetization M and the resistivity ρ were measured in the series of (Ag_{1 - x} Au_x)_0.9 Mn_0.1 alloys with x = 0, 0.007, 0.03, and 0.05. The difference between the values of zero field cooled and field cooled R_s, below the SG transition temperature, clearly increased with the amount of Au impurities. The dependence of the chirality contribution to R_s on the DM anisotropy is discussed in relation to the theoretical work for the chirality-driven anomalous Hall effect in weak coupling regime.
