报告摘要:
The real space observation of spin structures with atomic resolution is a long-time dream in magnetic imaging which was realized by the development of spin-polarized scanning tunneling microscopy (Sp-STM). This technique provides deep understandings of the structure, electronic and magnetic properties at the surface. In this talk, I will briefly introduce the basic principles and operating modes of Sp-STM together with the discoveries of a few novel types of noncollinear magnetic structure on the atomic scale. In particularly, I will introduce our recent observation of van der Waals stacking dependent interlayer magnetic coupling in epitaxially grown two-dimensional magnetic semiconducting bilayer.
