Achieving Large and Anisotropic Spin‐Mediated Thermal Transport in Textured Quantum Magnets

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
An advanced solvent‐cast cold pressing method is developed to synthesize highly textured quantum magnets. By aligning spin chains in Ca2CuO3 perpendicular to the pressing direction, a spin‐mediated thermal conductivity of 10 ± 1 W m⁻¹ K⁻¹ is achieved, the highest reported for polycrystalline quantum materials.
