论文摘要
srcute $ _2 $ o $ _6 $由旋转的3维安排 - $ \ frac {1} {2} {2} $ cu $^{2+} $ ions。第一，第二和第三个邻居相互作用分别将cu $^{2+} $矩矩为孤立的三角形网络，这是一个高度沮丧的超级熟练晶格，由角落共享三角形和反铁磁链组成。其中，连锁相互作用在Srcute $ _2 $ o $ _6 $中占主导地位，而其他两种相互作用导致沮丧的链间耦合，在抑制温度下导致长距离磁顺序。在本文中，我们使用MUON松弛光谱和中子衍射研究SRCUTE $ _2 $ o $ _6 $中的磁性特性，并呈现低温磁性结构。
SrCuTe$_2$O$_6$ consists of a 3-dimensional arrangement of spin-$\frac{1}{2}$ Cu$^{2+}$ ions. The 1st, 2nd and 3rd neighbor interactions respectively couple Cu$^{2+}$ moments into a network of isolated triangles, a highly frustrated hyperkagome lattice consisting of corner sharing triangles and antiferromagnetic chains. Of these, the chain interaction dominates in SrCuTe$_2$O$_6$ while the other two interactions lead to frustrated inter-chain coupling giving rise to long range magnetic order at suppressed temperatures. In this paper, we investigate the magnetic properties in SrCuTe$_2$O$_6$ using muon relaxation spectroscopy and neutron diffraction and present the low temperature magnetic structure.
