论文摘要
我们报告了使用改变游戏规则的技术（通过晶体生长期间的磁场应用磁场）“野外编辑”晶体结构（从短语“基因组编辑”）中合成的自旋耦合单晶中的新量子状态。这项研究旨在从根本上解决当今研究社区面临的重大挑战：大量的理论工作预测了异国情调的状态，用于强旋转轨道耦合，相关的材料，迄今为止已经满足了非常有限的实验确认。这些明显的差异主要是由于这些材料对结构扭曲的极端敏感性。这里提出的结果表明，“现场编辑的”材料不仅扭曲了得多，而且在其“非编辑”对应物中表现出了新现象。现场编辑的材料包括4D和5D过渡金属氧化物的阵列，此处介绍的三种代表性材料为BA4IR3O10，Ca2RUO4和SR2IRO4。这项研究为发现新的量子状态和材料而言，提供了一个全新的范式。
We report new quantum states in spin-orbit-coupled single crystals that are synthesized using a game-changing technology that "field-edits" crystal structures (borrowing from the phrase "genome editing") via application of magnetic field during crystal growth. This study is intended to fundamentally address a major challenge facing the research community today: A great deal of theoretical work predicting exotic states for strongly spin-orbit-coupled, correlated materials has thus far met very limited experimental confirmation. These conspicuous discrepancies are due chiefly to the extreme sensitivity of these materials to structural distortions. The results presented here demonstrate that the "field-edited" materials not only are much less distorted but also exhibit novel phenomena absent in their "non-edited" counterparts. The field-edited materials include an array of 4d and 5d transition metal oxides, and three representative materials presented here are Ba4Ir3O10, Ca2RuO4, and Sr2IrO4. This study provides an entirely new paradigm for discovery of new quantum states and materials otherwise unavailable.
