Scanning Tunneling Microscopy Study on Spintronic Emergent Materials

We present here the study of scanning tunneling microscopy (STM) on emergent materials with spin characteristics. Scanning tunneling spectroscopy (STS) is used to monitor the local electronic structure in nanometer scale for material surface, and further with help of a magnetic tip, can be spin-sensitive, becoming spin-polarized STM. Several examples will be given in this talk.
