自旋极化扫描隧道显微镜的研究进展

Research progress in the spin-polarized scanning tunneling microscopy

自旋极化扫描隧道显微镜(spin-polarized scanning tunneling microscope,SP-STM)将扫描隧道显微镜(scanning tunneling microscope,STM)的实空间分辨率和对自旋敏感的磁成像技术结合起来,已经成为人们研究纳米磁性物理的最有效工具之一.文章介绍了SP-STM的工作原理及其在低维磁性物理领域的应用和最新进展,如对磁性薄膜、磁性纳米岛、磁性原子及不共线结构的研究等,并对我国在这一领域的研究现状和发展前景进行简要评述.

Spin-polarized scanning tunneling microscopy（SP-STM） is one of the most effective tools for the study of nanomagnetic physics as it can combine real-space atomic resolution with spin imaging.In this review we introduce the principles of SP-STM and its recent applications in the field of low-dimensional magnetic physics,such as in the analysis of magnetic films,nano-islands,atoms,and nonlinear structures.The current state-of-the-art and future developments of this field in China are also discussed.
