Abstract
The thermal evolution of the crystal structure of PrSr3Co1.5Fe1.5O10–d, a member of the n = 3 family of Ruddlesden-Popper compounds, has been studied by means of variable temperature synchrotron X-ray powder diffraction combined with room temperature neutron diffraction studies. This structure takes the ideal tetragonal I4/mmm (n°139) space group. The possibility of symmetry lowering to the Pbca (n°61) space group by slight tilting and rotation of the oxygen atoms around the octahedral B site is discussed. The non linear thermal expansion of the compound in air is caused by a chemical expansion accompanying the loss of oxygen that comes in addition to normal thermal expansion. A mechanism describing the creation of oxygen vacancies is proposed.
