Disorder-based cluster Monte Carlo algorithm and its application in simulations of magnetization processes

The paper presents a modification of the so-called adding probability used in the Monte Carlo cluster algorithms. Certainly, the probability formula was supplemented by an entropy factor, depending on the local disorder of some selected properties of the studied system. The idea bases on the fact that disorder of some physical properties may affect clusterization of the system. The proposed modification enhances effectiveness of the simulations that is especially important in analysis of magnetization processes of irregular multiphase systems. In order to prove correctness of our approach a set of reverse magnetization curves was simulated for the systems composed of magnetically hard and soft phases. (C) 2018 Elsevier B.V.
