Computer simulation of growth and magnetic properties of quasi 2D magnetic cluster

Abstract

The computer simulation of the formation of 2D magnetic cluster is performed. It is shown that the magnetic interaction between growing cluster and randomly walking atoms results in the cluster elongation in the cluster magnetization direction. The features of microwave field absorption (FMR or SPR signals) in thin granular film consisting of elongated clusters are discussed. Magnetic resonance measurements can provide the detailed information on shape anisotropy of the particles and give an evidence for considered model of magnetic cluster growth.
