摘要：

In order to understand spin glass freezing process we measured ac-susceptibilities and thermoremanent magnetizations in Fe0.05TiS2 and analyzed the results by considering the distribution of relaxation times. We adopted two distribution functions. One is a conventional modified Debye distribution function and the other is a rectangular distribution function. We conclude that the latter is more appropriate and its parameter follows a power law, being consistent with previous results.
