- Summary
- The spin dynamics of a spin glass alloy Cu/sub 78/ /sub 7/Mn/sub 21/ /sub 3/ have been studied by neutron inelastic scattering. Measurements have been made at 20/sup 0/K, 150/sup 0/K, and 290/sup 0/K by the constant E mode of operation. Magnetic excitations with rather large energy transfer have been observed around the (1-1/2 O) and the (1-1/2+-delta O) magnetic diffuse peak positions above and below the spin freezing temperature (T/sub f/ approx. 90/sup 0/K). The results indicate the existence of strong space and time correlations of the spins over the temperature range of the measurements. The experimental data are well explained by a model of dynamically fluctuating spin clusters with a broad distribution of relaxation times.
