Magnon current
Webthe current formula of the magnon Hall conductivity is based on linear spin-wave theory (LSWT) [7], with little regard for the consequence of higher-order terms. Therefore, it is crucial to investigate how magnon damping affects magnon transport [31–33], and we introduce Cr2Ge2Te6 (CGT) as an ideal candidate. Weba magnon current in YIG layer via the conversion of the electron spin current to the magnon current [11–14]. In this case, the electron spin current and the magnon current are located in different spatial regions (electron spin current in Pt *[email protected] and magnon current in YIG, respectively), and the …
