The deformation of the 3d 5 electron shell of Fe 3+ ions in ZnFe 2 O 4 is investigated by Mössbauer spectroscopy without and with an external magnetic field of 6 T at 4.2 K. It is found that 3d 5 shell deformation observed by neutron spectroscopy brings about a quadrupole shift equal to ϵ3d = −0.030 mm/s. The magnitude of all other hyperfine interaction parameters of 57 Fe nuclei are also reported. Noncollinear arrangements of Fe 3+ spins, inside clusters as well as in their local environments, are observed. Among the Fe 3+ ions in the octahedral B‐sites five different magnetic configurations are distinguished.
