Abstract :
The low-temperature spin resonance measurements in a variety of metallic and non-metallic spin glasses and reentrant alloys, over an extended frequency range (2- 35GHz), reveal a universal behavior of the resonance linewidth and the existence of a ´resonant´ anomaly in concentrated metallic spin glasses. The results clearly point to the absence of time-scale for spin dynamics in random magnets.
