Abstract
Proper modeling of the magnetization dynamics of the involved magnetic nanoparticles (MNPs) is still one of the open challenges in magnetic particle imaging (MPI) particularly in the multi-dimensional excitation case of Lissajous-type. In this simulation study we focus on the immobilized and oriented MNP case and we investigate similarities and differences between the Fokker-Planck Néel model and an equilibrium model taking into account uniaxial anisotropy.
