Spin+Orbit Coupling: Orbitronics and spin-orbit effects (A01)

项目A01探索轨道电子学领域，包括用于有效自旋切换的新型电流诱导轨道扭矩。这些力矩是基于轨道霍尔效应和轨道拉什巴·埃德尔斯坦效应产生的轨道角动量，这些效应的效率可能比自旋的等效效应高一个数量级。我们将研究这些机制以及轨道角动量到自旋的转换，最终导致扭矩的产生。除了自转和轨道扭矩外，在对称破缺的这些系统中还会产生自扭矩。我们确定扭矩的来源，并确定导致这些扭矩的机制。最后，我们研究了所有这些力矩对选定的反铁磁系统的影响，以优化具有这种磁序的器件的电流感应开关。

Project A01 explores the field of orbitronics including novel current-induced orbital torques for efficient spin switching. These torques are based on the generation of orbital angular momentum by the orbital Hall and orbital Rashba Edelstein effects that can be orders of magnitude more efficient than the equivalent effects for spin. We will study these mechanisms and the conversion of orbital angular momentum to spin that eventually leads to the generation of torques. Beyond spin and orbital torques, self torques are generated in these systems with symmetry breaking. We identify the torque origin and determine the mechanism leading to these torques. Finally, we study the effects of all these torques on selected antiferromagnetic systems to optimize the current-induced switching of devices with such magnetic order.
