Origin of the intermediate-temperature magnetic specific heat capacity in the spin-liquid candidate Ca${}_{10}$Cr${}_7$O${}_{28}$

Joe Crossley, Chris Hooley

We present several approximate calculations of the specific heat capacity of the model for Ca${}_{10}$Cr${}_7$O${}_{28}$ proposed by Balz et al. [Phys. Rev. B 95, 174414 (2017)], using m…
