论文摘要
过渡金属卤化物可以容纳各种新现象，例如单层极限中的磁性，量子自旋液体和螺旋旋转液态状态以及拓扑元音和声子。高质量的单晶对于通过非弹性中子散射进行研究是必要的。在本文中，我们回顾了一种鲜为人知的蒸气运输技术，自选择的蒸气增长，并使用此技术报告了我们的过渡金属卤化物的增长。我们报告了RUCL $ _3 $，CRCL $ _3 $，RU $ _ {1-X} $ CR $ _X $ CL $ CL $ _3 $和CRBR $ _3 $的可观单晶的增长和特征。为了加快开始粉末向单晶的转化，我们通过在适当的温度范围内冷却生长安培来修改该技术。我们的工作表明，自选择的蒸气传输技术可以提供大型的过渡金属卤化物的单晶，这表明其提供了高质量的量子材料的单晶的潜力。
Transition metal halides can host a large variety of novel phenomena, such as magnetism in the monolayer limit, quantum spin liquid and spiral spin liquid states, and topological magnons and phonons. Sizeable high quality single crystals are necessary for investigations of magnetic and lattice excitations by, for example, inelastic neutron scattering. In this paper, we review a less well-known vapor transport technique, self-selecting vapor growth, and report our growths of transition metal halides using this technique. We report the growth and characterizations of sizable single crystals of RuCl$_3$, CrCl$_3$, Ru$_{1-x}$Cr$_x$Cl$_3$, and CrBr$_3$. In order to expedite the conversion of starting powder to single crystals, we modified the technique by cooling the growth ampoule through an appropriate temperature range. Our work shows that the self-selecting vapor transport technique can provide large single crystals of transition metal halides, demonstrating its potential for providing high quality single crystals of quantum materials.
