Field-Free, Deterministic Giant Spin-Orbit Torque Switching of 1.3 T Perpendicular Magnetization With Symmetry-Lifted Topological Surface States

{{output}}
The field-free control of perpendicular magnetization using spin-orbit torque (SOT) is a key challenge in spintronics, simplifying design and integration for both memory and logic applications. Unlike conventional heavy metal/ferromagnet heterostructures that ... ...
