报告摘要：The intrinsic topological insulator MnBi₂Te₄ has emerged as a fascinating platform due to its unique intertwining of magnetism and topology within the same material. This interplay gives rise to a range of intriguing phenomena, including the quantum anomalous Hall effect and the axion insulator state. In this talk, I will present our discovery of quantum metric nonlinear transport in even-layer MnBi₂Te₄. This quantum metric nonlinear transport acts as an intrinsic nonlinear response, independent of scattering time. Our findings open a new avenue for probing the quantum metric through nonlinear transport, offering potential applications in the design of magnetic nonlinear devices. Additionally, I will discuss our observation of highly tunable current-induced magnetization switching in MnBi₂Te₄.
