摘要

Superconductivity in some materials can be induced or tuned by chemical substitution,external pressure and magnetic field.Among these control parameters,pressure is a "clean" way to produce or manipulate superconductivity of matters without changing their chemistry. Recently,a new finding from Prof.Zhao Zhongxian's group at Institute of Physics,Chinese Academy of Sciences,demonstrated an unexpected superconducting phenomenon in a newly discovered iron selenide based superconductors under pressure condition.In this investigation,Prof.Sun Liling,a member of this group,and her colleagues in collaboration with Prof.
