概要
- 論文の詳細を見る
We study the Monte Carlo simulation on the two-dimensional -I-J Ising spinglass aiming to clarify the relation between behavior of individual spins and spinclusters in each sample and common spin glass properties of the system. Par-ticularly relaxation times of individual spins are evaluated and their temperaturedependences are examined. Making use of data obtained, we discuss in detail spin-freezing process in this model for spin glass. One of our most interesting findingsis that spin relaxation processes at temperatures '7'>0.8.7 obey Fulcher's law withT.:0.5./, implying that the characteristic relaxation time of the system may di-verge at T..
