摘要：
(I) Ba45Ca1.5Nd2Fe4O15 and (II) Ba5CaSm2Fe4O15 were prepared and investigated by a single-crystal X-ray technique. Both compounds crystallize in the space group C6v4-P63mc. (I): a = 11.6244; c = 6.9205 A ̊; (II): a = 11.655; c = 6.987 A ̊; Z = 2. The incorporation of Ca2+ into two of four possible point positions will be discussed. The incorporation of Sm3+ ions into the Ba6Nd2Al4O15 type requires the presence of Ca2+ on the point position occupied statistically by Ba2+ and Ln3+. © 1990.
