Reduced-Order Modeling of Nanoparticle Magnetization Dynamics

Year: 2025

Type: article

Abstract: The coupled Brown-Néel rotation model formulates the nanoparticle magnetization dynamics as a system of ordinary differential equations that are computationally demanding to solve. In this work, we propose utilizing a proper orthogonal decomposition approach for reduced-order modeling of magnetization dynamics, providing significant computational speedup while preserving accuracy.
