Dependence of the thickness of non-magnetic surface layer on the size of superparamagnetic iron oxide nanoparticles
Iron oxide nanoparticles are of particular interest for medical applications as they are biocompatible and can be used for diagnostics, imaging, drug delivery and cancer treatment. For these and other applications understanding and controlling the magnetic properties is crucial. The debate about the magnetization distribution within these nanoparticles is ongoing. There is still no satisfying model that is able to explain the observed reduction of the saturation magnetization of the particles compared to the bulk material. Possible mechanisms that were suggested include a magnetic core shell structure with a magnetically depleted surface layer in addition to spin canting around defects within the particles, a homogeneous distribution of spin canting in the particle or the formation of antiphase domain boundaries due to lattice defects.
