Suppression of magnetic order in Sr3Fe2O4Cl2 by Fe-site substitution by cobalt.

Abstract:

The low-temperature topotactic reduction of Sr(3)Fe(2-x)Co(x)O(5)Cl(2) oxychloride phases with LiH allows the preparation of phases of composition Sr(3)Fe(2-x)Co(x)O(4)Cl(2) (0 ≤ x ≤ 1). The reduced phases adopt body-centered tetragonal structures which are isostructural with Sr(3)Fe(2)O(4)Cl(2) and contain square-planar (Fe/Co)O(4) centers connected into apex-linked sheets, analogous to the CuO(2) sheets present in superconducting cuprate phases. As the cobalt concentration in Sr(3)Fe(2-x)Co...
