利用扫描隧道显微镜、角分辨光电子能谱和超导量子干涉仪系统地研究了Gd取代的Bi 2Se 3（以Bi 1.98Gd 0.02Se3为代表）的晶体结构、电子和磁性.发现3价垂直棒的Gd掺杂剂主要取代Bi原子。每个Gd 3+离子在体顺磁状态下具有与6.9 μ（B）一样大的磁矩。(C)2012年美国物理学会。[http：//dx.doi.org/10.1063/1.4729056]
The crystal structure, electronic, and magnetic properties of Gadolinium (Gd) substituted Bi2Se3-represented by Bi1.98Gd0.02Se3-were investigated systematically by scanning tunneling microscopy, angle-resolved photoemission spectroscopy, and superconducting quantum interference device. Gd dopants with valence of 3 vertical bar were mainly found to substitute Bi atoms. Each Gd3+ ion has a magnetic moment as large as similar to 6.9 mu(B) in the bulk paramagnetic state.
