我们报告了 kagome 磁体和 (，它可以被认为是深入研究的量子 kagome 磁体伏硼铁矿和维西尼矿 () 的 Co 类似物。对于每种化合物，基态似乎是反铁磁序。在低温下，施加磁场会导致类似变磁的转变，其中的转变描述为 反铁磁排列的倾斜力矩变为铁磁排列的倾斜力矩。这些基态和场感应态包括垂直于 kagome 平面的倾斜铁磁分量，这是 Dzyaloshinskii-Moriya 相互作用所青睐的。这些磁性特性可以通过物理学很好地表征。我们的发现将是朝着澄清 kagome 物理学迈出的一步，该物理学尚未得到彻底解决。 进行实验或理论研究。
We report the synthesis, crystal structure, and magnetic properties ofkagome magnetsand(, which can be recognized as Co analogs of the intensively researched quantum kagome magnet volborthiteand vesignieite(. For each compound, the ground state is seemingly-type antiferromagnetic order. At low temperatures, applying a magnetic field causes a metamagneticlike transition described by the transition in which antiferromagnetically aligned canted moments change to ferromagnetically aligned ones. These ground and field-induced states include a canted ferromagnetic component perpendicular to the kagome planes favored by Dzyaloshinskii-Moriya interactions. These magnetic properties are well characterized by thephysics. Our findings will be a step toward clarifying thekagome physics, which has not been thoroughly studied experimentally or theoretically.
