Abstract

This work explores how different parameters, e.g. magnetic anisotropy and core radius, influence the signal/spectrum of magnetic particles in a one-dimensional excitation field. Simulations are performed using a model considering both the mechanical and magnetization dynamics of the particle. The performed simulations show an increase of amplitude at higher harmonics for anisotropy constants within a certain range. This increase is also observed for different magnetic radii. The obtained knowledge can help to improve the performance of magnetic particles in magnetic particle imaging.
