## Description

- description: Yttrium and rare-earth iron garnets (R3Fe5O12) are ferrimagnetic insulators
    that have been widely studied for magnetic and spintronic applications. In this
    study, we report the thermal conductivity (κ) between 300 and 773 K for the single
    crystals of R3Fe5O12, where R = Y, Gd, Dy, and Yb. For Y3Fe5O12, the κ up to the
    Curie temperature (TC ≈ 555 K) can be described well with a pure phononic model,
    without considering conduction or scattering by the magnons. The iron garnets
    containing magnetic rare-earth ions exhibit smaller κ, with Dy3Fe5O12 showing
    the smallest values due to the strong interactions of heat-carrying phonons with
    the crystal field excitations of Dy3+ ions.
