R-Ferrite-type barium cobalt stannate, BaCo₂Sn₄O₁₁

H. Yamane, T. Ono and T. Yamada

Abstract: BaCo₂Sn₄O₁₁ is isotypic with R-ferrite, BaTi₂Fe₄O₁₁. The Co atoms fully occupy trigonal-bipyramidal sites () and are disordered with Sn atoms in octahedral sites (.2/m symmetry), as represented in the formula BaCoSn₂(Co_0.34Sn_0.66)₄O₁₁. Ba atoms are situated in a 12-fold coordinated site ( symmetry).
