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

点击翻译按钮获取中文摘要

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.
