摘要：

In the present work we report results from neutron and synchrotron radiation diffraction measurements that confirm the presence of a very weak phase transition in Sr2CuWO6 at about 600degreesC. This phase transition is continuous and changes the symmetry from 14/m at low temperature to another tetragonal phase at high temperature. On the basis of the experimental results we identify I4/mmm as the most probable space group for the high-temperature tetragonal phase.
