Abstract:

Spin-orbit torque (SOT) arising from spin-orbit coupling has gained much attention because it promises efficient magnetization switching in spintronic devices [1]. However, the switching is not purely electrical in laterally homogeneous structures. An extra in-plane magnetic field is required to achieve deterministic switching, and this is detrimental for device applications. Therefore, it is of crucial importance to find a way of field-free SOT switching of perpendicular magnetization along with reducing the switching current density for the widespread application of SOT technology.

In this talk, I first present various SOT materials which efficiently generated spin currents and associated SOTs to reduce field-free switching current [2]. Then, I will also show SOT-based spintronic devices such as MRAM-based process-in-memory [3] and physically unclonable functions (PUF) [4].
