Determining effective magnetic moment of multicore nanoparticles

Magnetic nanoparticles, a class of nanoparticles that can be manipulated by magnetic fields, have a wide range of technical and biomedical applications, including magnetic hyperthermia, targeted drug delivery, new magnetic storage media and nanorobots. Most commercial nanoparticles do not possess a single magnetic core but have a number of small magnetic crystals called crystallites.
