论文摘要
我们报告了BA5RU3O12的详细磁性，传输，热容量和中子衍射测量，该测量由隔离的RU3O12夹子组成。我们表明，该系统在60 K（TN）下开发了远程抗磁磁有序，而没有结构变形和金属隔离剂型跃迁，这与其他氟丁酸三聚体系统（如9R-Baruo3和Ba4ru3O10）形成了鲜明的对比。揭示了一个复杂的磁性结构，这归因于RU3O12夹子内不同晶体学位点上RU离子之间的竞争交换相互作用引起的磁性挫败感。
We report detailed magnetic, transport, heat-capacity, and neutron diffraction measurements of Ba5Ru3O12, a compound consisting of isolated Ru3O12 trimers. We show that this system develops long-range antiferromagnetic ordering at 60 K (TN) without structural distortion and metal-insulator-type transition, which is in sharp contrast to other Barium Ruthenate trimer systems such as 9R-BaRuO3 and Ba4Ru3O10. A complex magnetic structure is revealed which is attributable to the magnetic frustration due to competing exchange interactions between Ru ions on different crystallographic sites within the Ru3O12 trimer.
