We present the hydrothermal synthesis, as well as structural and chemical analysis of single crystals on the compounds EuCu$_{3}$(OH)$_{6}$Cl$_{3}$, Zn$_{x}$Cu$_{4-x}$(OH)$_{6}$(NO$_{3}$)$_{2}$ and haydeeite, MgCu$_{3}$(OH)$_{6}$Cl$_{2}$ all arising from the atacamite family. Magnetic and specific-heat measurements down to 1.8 K are carried out for these systems. EuCu$_{3}$(OH)$_{6}$Cl$_{3}$ has a frustrated antiferromagnetic Cu$^{2+}$ ground state with order at 15 K, a strong anisotropy and increased magnetization from Van Vleck paramagnetic Eu$^{3+}$ contributions. ZnCu$_{3}$(OH)$_{6}$(NO$_{3}$)$_{2}$ reveals antiferromagnetic order at 9 K and measurements on haydeeite single crystals confirm the ferromagnetic order at 4.2 K with the easy axis within the kagome plane. These results prove that the atacamite family presents a broad class of materials with interesting magnetic ground states.

Structural and magnetic properties of two branches of the Tripod Kagome Lattice family A$_{2}$RE$_{3}$Sb$_{3}$O$_{14}$ (A = Mg, Zn; RE = Pr, Nd, Gd, Tb, Dy, Ho, Er, Yb)
本文系统地研究了稀土三脚架Kagome晶格(TKL)族的两个分支的结构和磁性(A = Mg,Zn; RE = Pr,Nd,Gd,Tb,Dy,Ho,Er,Yb;这里,我们使用缩写\textit{A-RE},如在\textit{MgPr}中表示Mg $_{2}$ Pr $_{3}$ Sb $_{3}$ O $_{14}$),其补充了我们先前报道的关于\textit{MgDy}、\textit{MgGd}和\textit{MgEr} \cite{TKL}的工作。目前的易感性($χ_{dc}$,$χ_{ac}$)和比热测量揭示了各种磁性基态,包括\textit{MgPr},\textit{ZnPr}的非磁性单线态; \textit{MgGd},\textit{ZnGd},\textit{MgNd},\textit{ZnNd}和\textit{MgYb}的长程有序(LRO); \textit{MgDy},\textit{ZnDy}和潜在的\textit{MgHo}的长程磁荷有序态; \textit{ZnEr}、\textit{ZnHo}可能的自旋玻璃态; \textit{MgEr}、\textit{MgTb}、\textit{ZnTb}和\textit{ZnYb}化合物在80 mK以下不存在自旋有序。在这里观察到的基态既有相似之处,也有显着的差异,从父母烧绿石系统中发现的国家。特别是,虽然T…
Rare earth engineering in RMn$_6$Sn$_6$ topological kagome magnets
由于强相互作用可能导致新的拓扑相和拓扑跃迁,因此对具有电子关联的拓扑量子材料的研究是物理学的前沿。本文报道了一类可果美磁体RMn $_6$ Sn $_6$的量子输运性质与量子极限陈氏磁体TbMn $_6$ Sn $_6$的量子输运性质相似。拓扑输运的家庭,包括量子振荡与非平凡的Berry相位和大的反常霍尔效应所产生的Berry曲率场,点的存在,有质量的狄拉克费米子。我们的观察表明稀土磁性和拓扑电子结构之间的密切关系,表明稀土元素可以有效地工程在可果美磁体的陈量子相位。
