Structure-function relationship in Ba4Ru3O10 |
|
Résumé |
Recently the molecular orbital system in transition metal oxides is an attractive study because some researchers consider that these materials may have new ground state or transition. Ba4Ru3O10 contains the corner-shared Ru3O12 trimers made of three face-shared RuO6 octahedra, and each trimer is built upon two inequivalent Ru sites. In trimer, the Ru-Ru distance is shorter than that of Ru metal, so one can consider that this material assumes molecular orbital system. This material shows unique transition at 105 K, below which an antiferromagnetic order develops in only outer Ru sites. In this seminar, I introduce the single-crystalline x-ray diffraction study on Ba4Ru3O10, and I will discuss the electronic states using molecular orbital formation in the trimer. |
