WebInterestingly, the thermal Hall conductivity in Cr2Ge2Te6 shows the coexisting phonon and magnon contributions. Using an empirical two-component model, we successfully estimate the magnon contribution separate from the phonon part, revealing that the magnon Hall conductivity was 20 times smaller than the theoretical calculation. WebNevertheless, since topological magnon edge states contribute to the transverse thermal Hall conductivity, it has recently been demonstrated that the nontrivial topological nature of the magnonic bands can be manifested experimentally by the thermal Hall effect even in a charge-neutral spin system (23–26).
