✦ Synopsis


The structure of the n ΒΌ 4 Aurivillius oxide BaBi 4 Ti 4 O 15 has been studied at room temperature using powder neutron diffraction, and from 300 to 1000 K using synchrotron X-ray diffraction methods. The structure is orthorhombic (space group A2 1 am) at 300 K and transforms to a tetragonal (I4/mmm) structure near 700 K.

Rietveld refinement of powder neutron diffraction data has been used to study the crystal structures of the four-layer Aurivillius-phase ferroelectrics Bi 5 Ti 3 FeO 15 (at 251C) and SrBi 4 Ti 4 O 15 (at a series of temperatures up to 8001C). At 251C both materials adopt the polar orthorhombic space
