摘要：

Systematic studies of the frequency and temperature dependence of magnetic resonance in the most concentrated spin glass studied so far, a - (Fe//0//. //1//6Ni//0//. //8//4)//7//5P//1//6B//6Al//3, show the low T linewidth rise observed previously in randomized spin systems. The parameter describing this rise not only has the resonant anomaly seen earlier in other concentrated spin glasses but also exhibits a dramatic increase below 3. 5 GHz. The results are not adequately explained by any existing model.
