Abstract

Description

Nanosized spherical system of magnetic moments interacting indirectly via the RKKY mechanism is studied. The interaction energy that determines the temperature of the ferromagnetic ordering, depends strongly on the system size. Obtained in the mean-field approximation, dimensional and concentration dependencies of the Curie temperature testify to the necessity of taking into account the finite size of such systems to calculate their features. Results may concern both artificially constructed nanosystems and naturally arising formations (such as clusters of magnetic ions in diluted magnetic semiconductors, etc.).
