Abstract:

New complex oxides A4CuMn2O9 (A = Ca and Sr) belonging to the family of quasi-one-dimensional compounds A3n + 3mA′nB3m+nO9m + 6n (n = 3, m = 1) have been obtained by solid-phase synthesis from Ca and Sr carbonates and oxides CuO and MnO2. It was established that both oxides are incommensurate and can be characterized by two sublattices with the same a, but different c (c1 and c2) parameters. Their lattice parameters are a 9.195(2), c1 3.744(1), c2 2.580(1) Å for Ca4CuMn2O9 and a 9.602(2), c1 3.940(1), c2 2.593(1) Å for Sr4CuMn2O9. Magnetic susceptibility (χ) measurement results were interpreted with allowance for exchange-bound dimers Mn4+-Mn4+ and paramagnetic centers Cu2+. Magnetic measurements revealed the presence of calcium manganate CaMnO3 in Ca4CuMn2O9. The maxima on χ = f(T) dependences at 7.5 K (Sr4CuMn2O9) and 3.5 K (Ca4CuMn2O9) allowed us to surmise that the compounds in question have antiferromagnetic correlations. © 2002 Elsevier Science B.V.
