Abstract
We have calculated the pair interaction in CuMn by using the Friedel-Anderson model of local moments in metals. Over distances a<R<15a the decay of the interaction is considerably slower than 1/. With this coupling we are able to account for the magnitude of the spin interaction constant found for CuMn alloys in the ppm range; as well as the dependence on concentration of the glass temperature of more concentrated alloys after this temperature has been corrected for mean-free-path effects.
