中文摘要
合成了高质量的volborthite和vignieite样品,并测量了它们的物理性质,以阐明量子自旋液态的性质,这种状态有望出现在自旋为1/2 kagome的反铁磁体中。我们发现,磁斑岩是具有自旋液体基态的强有力候选者,两种化合物在磁化曲线上都表现出反常的磁化平台。
英文摘要
High quality samples of volborthite and vesignieite were synthesized and physical properties of them were measured to clarify the nature of the quantum spin liquid state, which is expected to appear in a spin-1/2 kagome antiferromagnet. We find that vesignieite is a strong candidate to have the spin liquid ground state, and both compounds show anomalous magnetization plateau in their magnetization curves.
