罕见的模型持有的螺母型候选者显示了对未来量子信息应用的希望

对称性破碎是诺贝尔奖获得者P.W.涉及的最基本元素之一，由新兴物理科学范式组成。欧洲杯线上买球安德森。一般已知的铁反顺序包括铁磁性，铁电和铁弹性顺序，它们分别打破了时间逆转对称性，空间逆转对称性并保留时间和空间逆转对称性，如图所示。

In the regard of symmetry transformation properties, there should be one more ferric order in the ferro symmetry jigsaw, i.e. ferrotoroidicity which violates both time- and space-reversal symmetries. Due to the special symmetry broken, there exist strong magnetoelectric coupling in ferrotoroidic materials, leading to promising applications in future quantum information technology.

Prof. Changqing Jin's team at IOPCAS recently discovered such a model-holding new compound Ba₆Cr₂S₁₀. Prof. Xiancheng Wang and Dr. Jun Zhanget.alof the team synthesized the new compound using high pressure technique. It was found that Ba₆Cr₂S₁₀consists of well separated dimerized face sharing CrS₆八面体链。在磁性状态下，旋转沿链方向偶联。链中二聚化和反平行自旋排列的组合破坏了时间和空间反转的对称性。由于空间反转对称性的破裂，观察到铁电性与自旋顺序一致。这些结果表明，理论预测的一维螺品螺状模型已在BA的真实材料中实现₆Cr₂S₁₀. As a rare model-holding ferrotoroidic candidate, the new compound can be considered"a starting point for the further exploration of the physics and applications of ferrotoroidicity, promising to future quantum information technology"报告科学家ChandQing Jin，Xiancheng Wang和Jun Zhang。

The work was jointly performed in collaboration with researchers from University College London, Rutherford Appleton Laboratory, Max Plank Institute for Chemical Physics of Solids etc. The study entitled "A ferrotoroidic candidate with well-separated spin chains" was published on高级材料欧洲杯足球竞彩34, 2106728(2022)athttps://doi.org/10.1002/adma.202106728. The study was supported by the National Science Foundation & the Ministry of Science and Technology of China.
