Dynamics of the relaxation from the metastable state for a Weiss ferromagnet

Динамика релаксации из метастабильного состояния для ферромагнетика Вейса

  • Published:
Il Nuovo Cimento B (1971-1996)

Summary

The relaxation from the metastable state for a Weiss ferromagnet is studied starting from first principles, in the framework of kinetic Ising models, by means of a continuous form of the master equation previously proposed. The obtained results suggest a microscopic description of thermoremanent magnetization phenomena.

Riassunto

Si studia il rilassamento dallo stato metastabile per un ferromagnete di Weiss partendo dai primi principi, nell’ambito dei modelli di Ising cinetici, utilizzando una forma continua della master equation precedentemente proposta. I risultati ottenuti suggeriscono una descrizione microscopica dei fenomeni di magnetizzazione termorimanente.

Резюме

Из первых принципов в рамках кинетических моделей Изинга, с помощью непрерывной формы ранее предложенного задающето уравнения, исследуется релаксация из метаставильного состояния для ферромагнетика Вейса. Полученные результаты представляют микроскопическое описание явлений термооста-точного намагничивания.
