赫氏石哈密顿量:单晶体上的$μ$ SR测量

Oren Ofer, Amit Keren, Jess H. Brewer, Tianheng H. Han, Young S. Lee

摘要:

我们提出了横向场μ子自旋旋转/弛豫测量自旋1/2 kagome反铁磁体Herbertsmithite单晶。我们发现,当磁场垂直于kagome平面时,自旋更容易极化。我们表明,不同方向之间的磁化强度的差异不能单独由Dzyaloshinksii-Moriya型相互作用来解释,并且存在各向异性的轴向相互作用。

英文摘要:

We present transverse field muon spin rotation/relaxation measurements on single crystals of the spin-1/2 kagome antiferromagnet Herbertsmithite. We find that the spins are more easily polarized when the field is perpendicular to the kagome plane. We demonstrate that the difference in magnetization between the different directions cannot be accounted for by Dzyaloshinksii-Moriya type interactions alone, and that anisotropic axial interaction is present.
