      abstract     = {Layered van der Waals (vdW) magnets are prominent
                      playgrounds for developing magnetoelectric, magneto-optic,
                      and spintronic devices. In spintronics, particularly in
                      spincaloritronic applications, low thermal conductivity (κ)
                      is highly desired. Herein, by combining thermal transport
                      measurements with density functional theory calculations,
                      this study demonstrates low κ down to 1 W m−1 K−1 in a
                      typical vdW ferromagnet Cr2Si2Te6. In the paramagnetic
                      state, development of magnetic fluctuations way above Tc =
                      33 K strongly reduces κ via spin-phonon scattering, leading
                      to low κ ≈ 1 W m−1 K−1 over a wide temperature range,
                      in comparable to that of amorphous silica. In the
                      magnetically ordered state, emergence of resonant
                      magnon-phonon scattering limits κ below ≈2 W m−1 K−1,
                      which will be three times larger if magnetic scatterings are
                      absent. Application of magnetic fields strongly suppresses
                      the spin-phonon scattering, giving rise to large
                      enhancements of κ. This study's calculations well capture
                      these complex behaviors of κ by taking the temperature- and
                      magnetic-field-dependent spin-phonon scattering into
                      account. Realization of low κ, which is easily tunable by
                      magnetic fields in Cr2Si2Te6, may further promote
                      spincaloritronic applications of vdW magnets. This study's
                      theoretical approach may also provide a generic
                      understanding of spin-phonon scattering, which appears to
                      play important roles in various systems.},
