Cooperativity and clusters properties in ferromagnetic spin transition systems

Abstract

Abstract A Swendsen-Wang cluster Monte Carlo dynamics simulation technique has been used to simulate a 2D-ferromagnetic Ising-type model for spin transition systems. In the purpose to investigate the link between the strength of cooperative interactions and the clusters properties, we shed light on the size and the number of clusters forming the system. Results show that clusters properties in highly cooperative systems are totally different from those in weakly cooperative ones.
