Dynamic magnetic response of multicore particles: the role of grain magnetic anisotropy and intergrain interactions — •Ekaterina Novak¹, Elena Pyanzina¹, Andrey Kuznetsov², and Sofia Kantorovich² — ¹Ekaterinburg, Russia — ²University of Vienna, Vienna, Austria

This study examines the magnetic properties of multicore magnetic nanoparticles (MMNPs) utilizing 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 inter-core magnetic interactions. 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.

Keywords: magnetic multicore nanoparticles; dynamic and static magnetic response; Langevin dynamics
