Abstract

The structure of Ba_1.1064CoO₃ has been solved in the (3+1)-dimensional formalism. The structure is described as a modulated chain composite with two subsystems, [CoO₃] and [Ba], respectively. The superspace group is R-3m(00γ)0s with a = 9.8842(20) Å, c = 2.4785(12) Å, and q = 0.5532(4) c^* (Z = 3). A saw-tooth function was used to model both the occupational and displacive modulations. Each atomic saw-tooth function is defined by its center x₄ along the fourth dimension, its width (A), and the maximum amplitude of the displacive modulation (δ). The paper describes how, as a first approximation, the columns (CoO₃) can be mainly described by a single free parameter, based on the height difference of the trigonal prisms and octahedra that constitute the transition metal chains. As a result, this superspace formalism requires only a small number of variables to be refined, compared to the conventional superstructure description.

 has been solved in the (3+1)-dimensional formalism. The structure is described as a modulated chain composite with two subsystems, [CoO<sub>3</sub>
] and [Ba], respectively. The superspace group is R-3m(00γ)0s with a = 9.8842(20) Å, c = 2.4785(12) Å, and q = 0.5532(4) c<sup>*</sup>
 (Z = 3). A saw-tooth function was used to model both the occupational and displacive modulations. Each atomic saw-tooth function is defined by its center x<sub>4</sub>
 along the fourth dimension, its width (A), and the maximum amplitude of the displacive modulation (δ). The paper describes how, as a first approximation, the columns (CoO<sub>3</sub>
) can be mainly described by a single free parameter, based on the height difference of the trigonal prisms and octahedra that constitute the transition metal chains. As a result, this superspace formalism requires only a small number of variables to be refined, compared to the conventional superstructure description.</s0>
