讲座摘要:
Despite nearly four decades of intensive research on various cuprates, the mechanism responsible for high-temperature superconductivity remains elusive. The investigation of high-temperature superconductors that do not rely on copper has become a focal point of intense exploration, as these materials may help elucidate the enigmatic mechanisms governing high-temperature superconductivity. In this talk, I will present neutron scattering studies of magnetic correlations and their interplay with superconductivity in various iron-based superconductors. Additionally, I will discuss our recent research that uncovered bulk superconductivity with a maximum critical temperature of around 30 K in pressurized trilayer nickelate La4Ni3O10-dsingle crystals.
