dc.description.abstract | We present several approximate calculations of the specific heat capacity of the model for Ca10Cr7O28 proposed by Balz et al. [Phys. Rev. B 95, 174414 (2017)], using methods including exact diagonalization, thermal pure quantum states, and high-temperature expansions. In none of these cases are we able to reproduce the magnitude of the zero-field specific heat capacity shown in the intermediate-temperature (∼5–15K) experimental data. We discuss possible reasons for the discrepancy, and what it might tell us about the magnetic Hamiltonian for Ca10Cr7O28. | |
