摘要
The n = 2 member in hexagonal perovskite manganate family A(n+1)Mn(n)O(3n+3)(Ca2O) was obtained in a complex composition La2Ba0.8Sr0.6Ca1.6Mn2O10, but simple hexagonal structure. It crystallizes in the hexagonal P6(3)/mmc space group [a = 5.63591(5) Angstrom, c = 16.2843(3) Angstrom, V = 447.948(9) Angstrom(3); Z = 2] and consists of double hexagonal perovskite layers (2H-type) and graphite-like [Ca2O] layer. The manganese octahedra share faces resulting in localized magnetic property. (C) 2002 Elsevier Science B.V. All rights reserved.
