Neutron powder diffraction data has been used to determine precise structures for four oxides in the series Ca 2− x Sr x CoWO 6 ( x =1, 1.5, 1.7, 2). The studies demonstrated that the symmetry increases with Sr content as a consequence of the gradu

Mixed perovskite samples, Ca1−xSrxTiO3, produced as solid ceramic materials, have been characterized using dynamic modulus and internal friction. These provide evidence for structural instabilities which have then been studied in detail using high-

The elastic stiffness constants of KSCN have been measured using a pulse-echo-overlap method at 10 MHz and compared to those for CsSCN. In both crystals it was found that transverse waves propagating normal to the minor planes encountered the greates
