Abstract
This study examines the magnetic properties of multicore magnetic nanoparticles (MMNPs) using Brownian dynamics simulations in conjunction with the Landau-Lifshitz-Gilbert equation. We demonstrate that the magnetic responses of MMNPs, both static and dynamic, are governed by a complex interplay between the cores magnetic anisotropy and the strength of intercore magnetic interactions. We show that for a single multicore in a liquid carrier, the distribution of the anisotropy axes inside does not impact its initial magnetic response. These insights are crucial for refining the design of multicore magnetic particles in various applications, including magnetic hyperthermia, data storage, and targeted drug delivery, where accurate control over magnetic characteristics is vital.
