Abstract

In the course of studies of alkaline earth oxo-neptunates Mössbauer spectra of237Np in SrNpO3 were taken. From the point of view of lattice symmetries two characteristically different sites for the Np ions were found. The transition temperature TC=(30.5±0.5) K was confirmed. The phase transition turned out to be of second order. Below TC the lattice orders antiferromagnetically.
