Abstract

The physical analytical conditions for coupling of superparamagnetic particles have been regarded in the present paper. The cases of two interacting superparamagnetic particles and superparamagnetic particle with another one being in single domain state were investigated. Assessments have been made for the critical period of magnetic moments' oscillations, determining the coupling of superparamagnetic particles. Some conclusions about the role of external magnetic field in this coupling were outlined.
