摘要本文综述了3He原子在固体基体上物理吸附得到的二维核磁体系的实验结果。近年来，人们对二维核反铁磁体和铁磁体进行了观察和研究，为自旋1/2磁哈密顿量提供了有用的模型系统，并得出了关于二维自旋系统磁有序的普遍有效性的结果。在吸附3He薄膜的实验研究中，讨论了海森堡、多自旋、鲁德曼-基特尔交换以及空位感应磁性。
Abstract We review in this paper the experimental results on two-dimensional nuclear magnetic systems obtained by physical adsorption of 3He atoms on solid substrates. Two-dimensional nuclear antiferromagnets and ferromagnets have been observed and studied in recent years, providing useful model systems for spin 1/2 magnetic Hamiltonians and leading to results of general validity on the magnetic ordering of two-dimensional spin systems. Heisenberg, multiple spin and Rudermann-Kittel exchange as well as vacancy-induced magnetism are discussed in the context of the experimental investigations of adsorbed 3He films.
