  • Collapse of density wave and emergence of superconductivity in pressurized-La4Ni3O10 evidenced by ultrafast spectroscopy

    Collapse of density wave and emergence of superconductivity in pressurized-La4Ni3O10 evidenced by ultrafast spectroscopy

    Figure 1 (a) shows the schematic of high-pressure optical pump-probe measurements in which a 120 fs pump pulse with 1.58 eV is used to excite the pressurized La4Ni3O10 sample, and another time-delayed probe pulse at 0.79 eV is used to record…

  • Orbital torque switching of room temperature two-dimensional van der Waals ferromagnet Fe3GaTe2

    Orbital torque switching of room temperature two-dimensional van der Waals ferromagnet Fe3GaTe2

    Orbital torque device based on 2D-vdW ferromagnet

    In 2D-vdW FM SOT heterostructures, the JS can be generated by SHMs [e.g., Pt34,35,36, Bi1.1Sb0.9Te2S137, and WTe239], and then these JS flow into 2D-vdW ferromagnets, exerting a torque that…
