A Study of Partially Substituted Sr8Ca6Cu24O41 Samples

A systematic study of samples of nominal composition A14Cu24O41 (A = alkaline-earth metal) with partial replacement on the alkaline-earth metal sites and on the Cu sites was carried out. Layered cuprates of the (Sr,Ca)2Cu2O3-CuO2 series with partial substitution by Gd, Dy, and Er for Ca were obtaine...

Zusammenfassung:	A systematic study of samples of nominal composition A14Cu24O41 (A = alkaline-earth metal) with partial replacement on the alkaline-earth metal sites and on the Cu sites was carried out. Layered cuprates of the (Sr,Ca)2Cu2O3-CuO2 series with partial substitution by Gd, Dy, and Er for Ca were obtained. X-ray powder diffraction analysis indicated that the solubility of the rare-earth metals in the Sr8Ca6Cu24O41 compound is limited to 2 atoms per formula unit. The Cu atoms in the structure of the spin-ladder phase can be replaced by Fe, Co, or Ni atoms up to the composition Sr8Ca6Cu23Fe1O41, Sr8Ca6Cu18Co6O41, or Sr8Ca6Cu23Ni1O41, respectively, whereas attempts to replace part of the Cu atoms by Mn or Zn atoms were not successful.
