Temperature and composition dependent structural investigation of the defect perovskite series Sr 1-x Ti 1-2x Nb 2x O 3 , 0?x?0.2

Brant, William R; Schmid, Siegbert; Gu, Qinfen; Withers, Raymond; Hester, James; Avdeev, Maxim


The crystal structure of the defect perovskite series Sr 1-xTi1-2xNb2xO3 has been investigated over a range of temperatures using high-resolution synchrotron X-ray diffraction, neutron diffraction and electron diffraction. Three distinct regions were observed: 0<x≤0.125 was a solid solution of Sr 1-xTi1-2xNb2xO3 with minor SrTiO3 intergrowth, 0.125<x≤0.2 was a pure Sr 1-xTi1-2xNb2xO3 solid solution adopting the cubic perovskite type structure (Pm3̄m) and for x>0.2 Sr0.8Ti0.6Nb0.4O3 and Sr...[Show more]
