What is it about?
We report here two new methods for experimentally measuring the demagnetization factor of assemblies of superparamagnetic nanoparticles. To examine the underpinning mechanisms and to relate current theory to these new methods, a model was created that examined the free poles on the constituent particles’ surfaces.

Why is it important?
Understanding how assemblies of magnetic nanoparticles respond when placed in a magnetic field is of great interest and importance in the area of bio-medical research and its application to treatment of cancers.
