Single crystals of SrxBa1-xNb2O6 (0.26 a parameter monotonically increases with increasing of temperature, while the c parameter decreases up to the phase transition temperature TC, and the next it begins increasing slowly. It was ascertained that with the increase of the Sr concentration in the studied crystals the changes of the lattice parameters were observed. They can be described according to the following relations: a = - 2.418 • 10-5 x2 + 1.050 • 10-3 x + 12.479 Å and c = - 0.0015 x + 4.0216 Å. Basing on the obtained results the character of the phase transition was able to do. |
