摘    要：This lecture covers the application mechanism and electronic behavior of new discovered iron-based superconductor, focusing mainly on the connectivity and its effect on the critical current density. Initially, the superconductivity as well as the discovery of the iron-based superconductor will be briefly reviewed and then the talk will discuss: (1) coexistence of the strong and weak links discovered by magnetic and transport critical current density study (2) a model coexistence of strong and weak links was proposed and proved by the flux creep calculation (3) anomalous tail effect on resistivity transition discovered in iron-based superconductor and the numerical simulation (4) pairing mechanism and electronic behavior of superconducting SmFeAsO_0.75 and Sc₅Ir₄Si₁₀.
