香港城市大学博士后

报告摘要

Superconductivity and ferromagnetism are naturally competing, while their interplay can give rise to exotic quantum phases, such as triplet pairing, exemplified by heavy-fermion compounds like UTe2, where magnetic fluctuations stabilize multiple superconducting states. However, such phenomena have remained elusive in high-temperature superconductors. Here I will introduce the coexistence of ferromagnetism and superconductivity in infinite-layer nickelates, along with the signatures of magnetic-fluctuation-mediated pairing and a potential quantum critical point within the phase diagram. Our findings establish infinite-layer nickelates as a unique platform for high-temperature ferromagnetic superconductivity, opening new avenues for discovering and manipulating unconventional quantum phases in strongly correlated materials.
