Description
We have investigated the existence of a structural distortion associated to the k = (1/2 0 1/2) orbital ordering recently proposed to explain the magnetic structure of RNiO3 perovskites (R = rare earth). Our results on a 154SmNiO3 powder sample indicate that, if existing, the associated superstructure reflections are as a maximum 104 times smaller than the largest nuclear reflection.
