Spin+Current: Angular momentum transport by magnons, spins, and orbits (B02)

B02项目研究选定物质系统的角动量输运，以了解诸如输运长度尺度等关键性质。这包括反铁磁体中的磁子自旋输运和交替磁体中的自旋输运，特别是我们想要展示氧化物系统中的变磁性质。基于我们对传统磁子自旋输运的理解，我们将探索本质上纠缠在反铁磁体中的关联磁子的量子输运。除了自旋，我们还将探索轨道角动量输运，这是基于非常不同的机制。利用对输运的理解，最终目标将是通过使用YIG/GIG等异质结构来控制输运，以展示磁振子自旋阀效应。

Project B02 investigates angular momentum transport of selected material systems to understand key properties such as the transport length scales. This includes magnonic spin transport in antiferromagnets and spin transport in altermagnets, where in particular we want to demonstrate altermagnetic properties in oxidic systems. Based on our understanding of conventional magnonic spin transport, we will explore emergent quantum transport of correlated magnons that are intrinsically entangled in antiferromagnets. Beyond spin, we will probe orbital angular momentum transport, which is based on very different mechanisms. Using the understanding of the transport, the final aim will be to control transport by using hetero-structures such as YIG/GIG to demonstrate a magnon spin valve effect.
