报告摘要:

The first question we pose while studying any new family of correlated electron materials is the question concerning the internal structure: what are the crystalline and magnetic building blocks and how are they arranged? The second question concerns the microscopic dynamics: how do these building blocks move and what are their internal degrees of freedom? These herculean tasks can be accomplished by modern neutron and synchrotron X-ray scattering. Especially, neutron scattering is a unique powerful tool to solve magnetic structures and determine magnetic excitations and fluctuations. In this talk, I will present our work on iron-based superconductors & intermetallic compounds, focusing on the studies of crystalline and magnetic structures as well as spin dynamics [l-8], investigated mainly by neutron scattering technique.
