Classification of magnetic nanoparticle systems—synthesis, standardization and analysis methods in the nanomag project

This article belongs to the Special Issue "Magnetic Nanoparticles 2015".-- This is an open access article distributed under the Creative Commons Attribution License (CC BY).This study presents classification of different magnetic single- and multi-core particle systems using their measured dynamic magnetic properties together with their nanocrystal and particle sizes. The dynamic magnetic properties are measured with AC (dynamical) susceptometry and magnetorelaxometry and the size parameters are determined from electron microscopy and dynamic light scattering. Using these methods, we also show that the nanocrystal size and particle morphology determines the dynamic magnetic properties for both single- and multi-core particles. The presented results are obtained from the four year EU NMP FP7 project, NanoMag, which is focused on standardization of analysis methods for magnetic nanoparticles.This project has received funding from the European Commission Framework Programme 7 under grant agreement no 604448.
