概要
- 論文の詳細を見る
A method is proposed for determining volume ratios of domains in a poly-domain specimen of perovskite crystals with the space group 14/mcm ; the ratiosare fundamental parameters in determining the crystal structure. The method isbased on measuring relative intensities of triplets of Bragg reflexions with specialindices and is applied to structure determinations of SrTi0. and KMnF.. Adiscussion is given of refinement of the structure; a difficulty in a least squarescalculation owing to a correlation between structural parameters is emphasized.The use of accurate lattice-constant data together with a conventional structureanalysis is recommended.
