本文提出了一个研究单变相到多变相的一级相变中的滞后和雪崩的模型。该模型是基于亚稳态动力学随机场Potts模型的修正,在最近邻处增加了一个截断的偶极相互作用项。我们的研究重点是磁滞回线的性质,三维(3D)微结构的形成和雪崩统计。

英文摘要:
A model for the study of hysteresis and avalanches in a first-order phase transition from a single variant phase to a multivariant phase is presented. The model is based on a modification of the Random Field Potts model with metastable dynamics by adding a dipolar interaction term truncated at nearest neighbors. We focus our study on hysteresis loop properties, on the three-dimensional (3D) microstructure formation and on avalanche statistics.
