论文摘要
探索带有旋转轨道纠缠的jeff = 1/2矩的基于稀疏的（RE）的kagome晶格磁铁将为研究外来磁相提供新的平台。在这里，我们报告了一个新的RE3BWO9（re = pr，nd，gd-ho）的新家族，具有排列在Kagome晶格上的磁性RE3+离子的boratotungstates，并执行其结构和磁性表征。这种串行化合物在六角形协调的结构中与空间群p63（第173号）结晶，其中磁性RE3+离子在AB平面内扭曲了Kagomé晶格连接，并以C轴沿AB型的方式堆叠。层间的重新分离与内部距离的分离相当，形成了RE3+离子的3维（3D）交换耦合磁框架。 The magnetic susceptibility data of RE3BWO9 (RE=Pr, Nd, Gd-Ho) reveal dominant antiferromagnetic interactions between magnetic RE3+ ions, but without visible magnetic ordering down to 2 K. The magnetization analyses for different RE3+ ions show diverse anisotropic behaviors, make RE3BWO9 as an appealing Kagome-lattice antiferromagnet to explore exotic magnetic phases.
Exploration of rare-earth (RE)-based Kagome lattice magnets with spin-orbital entangled jeff=1/2 moments will provide new platform for investigating the exotic magnetic phases. Here, we report a new family of RE3BWO9 (RE=Pr,Nd,Gd-Ho) boratotungstates with magnetic RE3+ ions arranged on Kagome lattice, and perform its structure and magnetic characterizations. This serial compounds crystallize in hexagonal coordinated structure with space group P63 (No.173), where magnetic RE3+ ions have distorted Kagomé lattice connections within the ab plane and stacked in a AB-type fashion along c axis. The interlayer RE-RE separation is comparable with that of intralayer distance, forming 3-dimensional (3D) exchange coupled magnetic framework of RE3+ ions. The magnetic susceptibility data of RE3BWO9 (RE=Pr, Nd, Gd-Ho) reveal dominant antiferromagnetic interactions between magnetic RE3+ ions, but without visible magnetic ordering down to 2 K. The magnetization analyses for different RE3+ ions show diverse anisotropic behaviors, make RE3BWO9 as an appealing Kagome-lattice antiferromagnet to explore exotic magnetic phases.
