dc.description.abstract | Quasielastic Raman scattering arising from spin energy fluctuations is used to extract the magnetic specific heat. To test the applicability of a Raman scattering technique for probing magnetic specific heat, we choose three different classes of quantum magnets: (i) a quasi-1D s=1/2 antiferromagnetic chain CuSe2O5, (ii) a 3D Kitaev honeycomb magnet γ-Li2IrO3, and (iii) a coupled-spin tetrahedral system Cu2Te2O5Cl2. Despite distinct dimensionality, spin topology, and spin-exchange type, the three materials show a pronounced quasielastic response commonly, enabling the determination of the magnetic contributions to the specific heat. Our work demonstrates that a Raman spectroscopic method is useful, complementing the conventional thermodynamic method, in deriving the magnetic specific heat in quantum magnets. | - |
