Oxidation-induced ultrafast spin-to-orbital conversion at heavy-metal interfaces
Xiaoxue Zeng, Tianyi Zhang, Yaokai Niu +6
Oxidation engineering provides a route to control orbital degrees of freedom, yet its role in spin-to-orbital conversion remains largely unexplored. Here, we report an efficient sp…
