【 摘 要 】

The distribution of Sr in Sr3YB3O9 crystals was determined by anomalous X-ray scattering. The Sr3YB3O9 sample was grown by the floating-zone method in dry air. The Sr3YB3O9 crystal has three cation sites (3a, 3b, and 18f). The results of single-crystal structural analysis using anomalous X-ray scattering at the Sr K-edge suggested that Sr is distributed at the 3a site as well as it is at the chemically disordered 18f site.
