Abstract

Doped up: The incorporation of Zn²⁺ dopants in tetrahedral sites leads to the successful magnetism tuning of spinel metal ferrite nanoparticles (see picture). (Zn_0.4Mn_0.6)Fe₂O₄ nanoparticles exhibit the highest magnetization value among the metal ferrite nanoparticles. Such high magnetism results in the largest MRI contrast effects (r2=860 mm^-1 s^-1) reported to date and also huge hyperthermic effects.
