For Ising spin glasses Fe.TiS. (,v=0.05, 0.1, 0.2), to investigate the temperaturedependence of the relaxation time, ac-susceptibility measurements are made. Fre-quency dependences of spin glass transition tempe?"atures defined by the maximum ofthe ac-susceptibility are anal)zzed by four conventional equations. The appropriateequation for .X'=0.05 and ,v=0.l is the power law (for finite I"). For ,v=0.l it seemsthat the Fulcher law also describes the data. The appropriate equation for x=O.2 isthe Fulcher law. The results of the analyses suggest the existence of clusters of Fe-spins for high-Fe concentrations.Ising spin glass, ac susceptibility, spin glass transition temperature, frequencydependence, concentration dependence, power law, Fulcher law
