Abstract

The ac-susceptibility of a three-dimensional Ising spin glass Fe0.05TiS2 is analyzed above its spin glass transition temperature, in order to determine a distribution function g(In τ) of spin relaxation times τ. The probable function consists of a constant part at short times and a decreasing part at long times with a sudden cut-off. This form is consistent with g(In τ) simulated and attributed to be a spin glass critical dynamics by Takayama. There remain small disagreements between the data and the calculated values, suggesting the existence of a tail extending from the long-time end of the distribution function.
