Giant thermal magnetoconductivity in CrCl3 and a general model for spin-phonon scattering

The authors demonstrate giant thermal magnetoconductivity in the layered magnetic material CrCl3. An applied magnetic field acts to suppress a massive spin-induced phonon scattering, which restores the purely phononic thermal conductivity. The paper shows a quantitative description that has applicability in thermal transport measurements on 2D Dirac, topological, and candidate-Kitaev materials.
