项目摘要
The recently discovered antiferromagnet SrRu2O6 is a new example of a 4d-transition metal oxide with quasi-2D structure and long range magnetic order. Its unusually high magnetic ordering temperature of about 560 K makes it a promising model system for studying the interplay of spin and charge in a correlated electron system with high spin-orbit coupling. The project team will synthesize this material in pure and doped form and study its magnetic and dielectric properties. The project partners ask essentially for travel support which will allow linking the complementary activities at both sides. In particular, the partners will utilize both conventional and microwave-assisted hydrothermal synthesis for producing the materials. In addition to pure SrRu2O6, A-site and B-site doping in the AB2O6 structure will be performed, with B for example being the 3d V5+ or the 5d Ir5+ ions and A being, e.g., Ca2+, Ba2+, Mg2+, Zn2+. All materials will be thoroughly characterized by x-ray diffraction, chemical analysis, and magnetic studies. In order to understand the interplay of spin, charge, and structure, the Indian team will apply dielectric spectroscopy and nonlinear dielectric and magnetic susceptibility measurements. A first step towards devices will be done by liquid exfoliation. The German team will add information on the static and dynamic magnetic properties by using high-frequency Electron-Spin-Resonance-Spectroscopy and Muon-Spin-Rotation studies. The project will hence yield a comprehensive understanding of a new layered 4d material with potential relevance for application.
最近发现的反铁磁体SrRu2O6是具有准2D结构和长程磁序的4d过渡金属氧化物的新例子。其异常高的磁有序温度约为560K,使其成为研究具有高自旋-轨道耦合的关联电子系统中自旋和电荷相互作用的很有前途的模型系统。该项目团队将以纯和掺杂的形式合成这种材料,并研究其磁性和介电性能。项目合作伙伴基本上要求提供旅行支助,以便将双方的互补活动联系起来。特别是,合作伙伴将利用传统水热合成和微波辅助水热合成来生产材料。除了纯的SrRu2O6外,还将在AB2O6结构中进行A位和B位掺杂,其中B例如是3DV5+或5DIr5+离子,而A是例如Ca2+、Ba2+、Mg2+、Zn2+。所有材料都将通过X射线衍射、化学分析和磁性研究进行彻底的表征。为了了解自旋、电荷和结构的相互作用,印度团队将应用介电光谱和非线性介电和磁化率测量。迈向设备的第一步将是液体剥离。德国团队将通过使用高频电子自旋共振光谱和Muon自旋旋转研究来增加关于静态和动态磁性的信息。因此,该项目将产生对具有潜在应用意义的新的层状4d材料的全面了解。
