Annotation	The structure and magnetic arrangement of Zn0.34Fe2.53O4 in the form of spherical nanoparticles with the mean size of 14 nm, prepared by thermal decomposition method, have been studied by neutron diffraction at 10-300 K. The investigation provides detailed data on lattice parameters, interatomic bond lengths and angles, and ferrimagnetically ordered moments of iron ions in A and B crystallographic sites of the spinel structure. With a help of supplementary result of Mossbauer spectroscopy, the distribution of Zn and Fe ions between A and B sites is determined to (Fe0.823+Zn0.182+)A[Fe1.443+Fe0.272+Zn0.162+□0.13] BO4, where the B-site vacancy □0.13 quantifies the cation non-stoichiometry due to partial oxidation of the ferrite. Within a collinear model of ionic spins, this distribution agrees well with the spontaneous magnetization determined by magnetometry at 5 K of 103.6 Am2/kg equivalent to 4.22 μB per f
