This manuscript deals with the study of low dimensional cuprates, namely, the spin chains systems SrCuO₂ and Sr₂CuO₃. These two compounds exhibit highly anisotropic thermal conduction properties along the spin-chains direction, where magnetic thermal conduction contributes to the heat transport process via spinon excitations. Our study aims to highlight the mechanisms that govern the heat transport properties, particularly through the study of the scattering channels involving spinon, phonon and defects. The spinon (phonon)–defect scattering was probed by the intentional introduction of nonmagnetic dopants (1-2%) on the copper site, by: Mg²⁺, Zn²⁺, Pd²⁺ or Ni²⁺, or by the introduction of elements carrying different oxidation level on the st...
