Abstract
By calculating wave-number dependent frequency moments, the dynamical behavior of EupSr1-pS in investigated in the paramagnetic phase. The anomalous long time behavior in local ordering near the critical temperature is shown in addition to the usual slowing down phenomena. This is found very sensitive to the concentration p of the magnetic ions Eu2+.
