Ca 2 Fe 2 O 5 shows a first-order phase transition from space group Pnma to a modulated structure described in superspace group Immað00gÞs00. The transition starts at 947 K during heating and the reverse transition in cooling conditions starts at 923 K, as determined from differential thermal analys

The crystal structure of La 0.63 (Ti 0.92 ,Nb 0.08 )O 3 has been re5ned by the Rietveld analysis of CuK X-ray powder di4raction data collected at 233C. This material was con5rmed to have an A-site de5cient orthorhombic perovskite-type structure with double ideal perovskite ABO 3 units along the c-ax
