Magnetic nanoparticles of iron oxides have received extensive attention in the biomedical research, e.g. as prospective contrast agents for T2-weighted magnetic resonance imaging (MRI). The ability of a contrast agent to enhance the relaxation rate of 1H nuclei in its vicinity is quantitatively described by its relaxivity. We present the first case study considering ε-Fe2O3 nanomagnets for prospective application in biomedicine, in particular for MRI in ultra-high fields. The study is complemented by a thorough investigation of magnetic properties of the nanoparticles, revealing some interesting anomalies.
