Herein, the microwave-assisted sol-gel synthesis and thorough characterization of size-monodisperse zinc ferrite nanoparticles of spherical shape is reported. X-ray diffraction, ⁵⁷Fe Mössbauer spectroscopy and X-ray photoelectron spectroscopy all show that the material is both chemically and phase-pure and adopts a partially inverted spinel structure with Fe³⁺ ions residing on tetrahedral and octahedral sites according to (Zn_0.32Fe_0.68)^tet[Zn_0.68Fe_1.32]^octO_4±δ.
