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

A01计划探索轨道电子学领域，包括用于高效自旋开关的新型电流诱导轨道转矩。这些力矩是基于轨道Hall效应和轨道Rashba Edelstein效应产生的轨道角动量，它们比自旋的等效效应效率高几个数量级。我们将研究这些机制以及轨道角动量转化为最终产生力矩的自旋。除了自旋力矩和轨道力矩外，这些系统还产生自旋力矩。我们确定了扭矩的来源，并确定了导致这些扭矩的机制。最后，我们研究了所有这些转矩对选定的反铁磁系统的影响，以优化具有该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.
