Abstract

Materials with high thermal conductivity have attracted considerable attention for thermal management of electronic devices. Therefore, focusing on formability and anisotropic heat transfer, we fabricated glass-ceramics containing the spin-chain compound SrCuO2 and demonstrated its high thermal conductivity in the previous work, where SrCuO2 is known to exhibit high thermal conductivity owing to the presence of quasiparticles, i.e., spinons. In this study, we attempt to confirm the presence of spinons by analyzing temperature dependence of specific heat and investigate relationship between spinons and thermal properties.
