我们报告了由 3 He 吸附在镀有两个 HD 原子层的石墨上形成的单层二维固体的核磁化率的测量。观察到低密度固体，与 √7×√7 记录的结构一致，表现出大量的反铁磁交换。在 1 mK 附近观察到磁化率的明显尖点，表明存在磁相变。讨论了这个特征和其他特征随表面密度的演变
We report measurements of the nuclear magnetic susceptibility of the monolayer two-dimensional solid formed by 3 He adsorbed on graphite plated with two atomic layers of HD. A low-density solid is observed, consistent with a √7×√7 registered structure, which exhibits large antiferromagnetic exchange. A distinct cusp in the susceptibility is observed near 1 mK, suggestive of a magnetic phase transition. The evolution of this and other features with surface density is discussed
