Abstract

The influence of the Dzyaloshinsky-Moriya (DM) anisotropy on the extraordinary Hall coefficient R_s ≡ ρ _xy M, where ρ_xy is the extraordinary Hall resistivity and which contains the chiral susceptibility, is investigated on canonical spin glass alloys. The strength of the DM anisotropy of the alloys was changed systematically by doping with a third non-magnetic impurity. The Hall resistivity ρ_h, and the magnetization M were measured simultaneously in the series of (Ag_1-xAu_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 spin glass transition temperature, clearly increases with the amount of Au impurities. This indicates that the DM anisotropy plays an important role in the appearance of the chiral susceptibility in canonical spin glasses. The result is discussed in relation to recent proposals for the chirality mechanism of the Hall effect in canonical spin glasses.
