Superparamagnetism in Biomedicine

Superparamagnetism occurs in ferromagnetic nanoparticles, where in the absence of a magnetic field their total average magnetism in any direction (magnetization) appears to be zero. Once in the presence of an external magnetic field they become magnetized, with their magnetic moments aligning with the field.
