Modelling nanoparticles and their magnetic response in various environments

In this study, the magnetic behaviour of superparamagnetic nanoparticles in various environments is modelled, which have their clinical significance in e.g. the sentinel node biopsy. This was done using the Legendre expansion of two Fokker-Plank equations, one for Brownian and one for Néel relaxation. The voltage as measured with SPaQ can be approximated with the combined result of these. Based on verification with experimental data, it can be said that this model accurately reflects the behavior of the tested particles, with the exception of a flower-shaped particle.
