Dynamical behavior of two interacting magnetic nanoparticles

Laroze, D; Vargas, P.

Abstract

In the present work, we study the deterministic spin dynamic of a two interacting magnetic particles, with both dipolar and exchange interactions in the presence of an applied magnetic field. Due to the strength ratio of interactions, two time scales appear; a longer one associated with the exchange interaction and a shorter time scale associated with the dipolar interaction. We find that the magnitude of the total system magnetization is not constant; furthermore it is a fluctuating time-dependent function. © 2005 Elsevier B.V. All rights reserved.
