概要
- 論文の詳細を見る
Fluctuations related to the Belavin-Polyakov pseudoparticle play an important role in the decay of the metastable state, where external field reverse to the spontaneous magnetization is applied. The energy at the saddle point is of the order of the exchange constant unless the external field is much weaker than the anisotropy.
