Angular momentum transport is one of the cornerstones of spintronics. Spin angular momentum is not only transported by mobile charge carriers but also by the quantized excitations of the magnetic lattice in magnetically ordered systems. In this regard, magnetically ordered insulators (MOIs) provide a platform for magnon spin transport experiments without additional contributions from spin currents carried by mobile electrons. In combination with charge-to-spin current conversion processes in conductors with finite spin–orbit coupling, it is possible to realize all-electrical magnon transport schemes in thin-film heterostructures. Herein, an insight into such experiments and recent breakthroughs achieved is provided. Special attention is given to charge-current-based manipulation via an adjacent normal metal of magnon transport in MOIs in terms of spin-transfer torque. Moreover, the influence of two magnon modes with opposite spin in antiferromagnetic insulators on all-electrical magnon transport experiments is discussed.

磁序绝缘子中的全电磁振子输运实验

角动量传输是自旋电子学的基石之一。自旋角动量不仅由移动电荷载流子传输，而且还由磁有序系统中磁晶格的量子激发传输。在这方面，磁有序绝缘体 (MOI) 为磁振子自旋输运实验提供了一个平台，而无需来自移动电子携带的自旋电流的额外贡献。结合具有有限自旋轨道耦合的导体中的电荷到自旋电流转换过程，可以在薄膜异质结构中实现全电磁振子传输方案。在此，提供了对此类实验和最近取得的突破的深入了解。在自旋转移扭矩方面，特别注意通过 MOI 中磁振子传输的相邻正常金属进行基于充电电流的操纵。此外，还讨论了反铁磁绝缘体中具有相反自旋的两种磁振子模式对全电磁振子输运实验的影响。
