Abstract

The temperature dependence of superlattice reflections has been investigated, in Ba 2NaNb 5O 15, by X-ray oscillation photographs taken along the c-axis. The reflections vanish above the 300°C ferroelastic transition. This result confirms that the transition's order parameter corresponds to the Z-point of the Brillouin zone of the high-symmetry phase.
