Studies of spin dynamics in low-dimensional systems are important from both fundamental and practical points of view(1),(2). Spin-polarized scanning tunnelling microscopy allows localized spin dynamics to be characterized and plays important roles...
Scientific Reports   4    Oct 2014   [Refereed]
Detection of the extremely weak signals in spectroscopy over an extremely wide frequency region is central to diverse sciences, including materials science, biology, astronomy and chemistry. Here we show a new type of atomic-scale spectroscopy, he...
