Superparamagnetic materials consist of individual domains of elements that have ferromagnetic properties in bulk. Their magnetic susceptibility is between that of ferromagnetic and paramagnetic materials

The figure illustrates the effect of a superparamagnetic material (grey circle) on the magnetic field flux lines (blue). Examples of superparamagnetic materials include iron-containing contrast agents for bowel, liver, and lymph node imaging.
