Influence of DzyaloshinskyMoriya interactions on the critical behavior of metallic spin glasses J. Appl. Phys. 61, 4097 (1987); 10.1063/1.338540Observation and interpretation of a new transition observed via the field dependent ac susceptibility of the spin glass CuMn (abstract)The effect of gradually changing the background matrix in which Mn ions are imbedded has been investigated in the spin-glass system CU 95 _ x Au .. Mus by means of low-field Hall effect and ac susceptibility measurements. For the Cu~rich alloys a substantial positive anomalous Han coefficient is found arising from skew scattering of Dzyaloshinsky-Moriya origin which peaks in each case at the freezing temperature. The concentration x = -50% appears to be critical in that (a) the anomalous Hail coefficient changes sign, (b) Pelf undergoes a change of 0.30, and (c) a fairly sudden change of the ordinary Hall coefficient occurs. These results suggest the Mn ions suddenly acquire additional orbital angular momentum at this composition.
