A new concept for quantitative nanoscale imaging with magnetic contrast: Synchrotron x-ray enhanced scanning tunneling microscopy

Abstract

The combination of synchrotron x-rays with scanning tunneling microscopy provides a promising new path towards the imaging of nanoscale structures with chemical, electronic, and magnetic contrast. While a scanning probe provides the high spatial resolution measuring x-ray magnetic circular dichroism allows the direct quantification of magnetic moments. This capability has the potential to broaden and deepen the general understanding of nanomagnetism.
