Generation of twisted magnons via spin-to-orbital angular momentum conversion
Z. -X. Li, Zhenyu Wang, Yunshan Cao +1
Twisted magnons (TMs) carrying orbital angular momentum (OAM) have attracted much attention from the magnonic community. The fabrication of such novel magnon state however is still…
Nonreciprocal Spin Waves Driven by Left-Hand Microwaves
Zhizhi Zhang, Zhenyu Wang, Huanhuan Yang +3
It is a conventional wisdom that a left-hand microwave cannot efficiently excite the spin wave (SW) in ferromagnets, due to the constraint of angular momentum conservation. In this…
