报告摘要：
Despite nearly four decades of intensive research on cuprate superconductors, the microscopic pairing mechanism responsible for high-temperature superconductivity remains elusive. This long-standing challenge has driven the search for copper-free unconventional superconductors, which can provide complementary insights and tighter constraints on the essential ingredients for high-Tc pairing.

In this talk, I will present neutron scattering studies of magnetic correlations and their interplay with superconductivity in representative iron- and chromium-based superconductors. I will then discuss our discovery of bulk superconductivity in pressurized trilayer nickelate single crystals. Finally, I will highlight recent results on spin order and spin dynamics in nickelates and discuss their implications for the pairing mechanism.
