a The heat capacity (Cp) of CoTe6O13 from 1.8 K to 40 K measured at 0 T, 3 T, 6 T, and 9 T field, displayed by black, red, green, blue dots and curves, respectively. The gray open squares display the heat capacity of the non-magnetic reference compound MgTe6O13. b The magnetic heat capacity over temperature (Cmag/T) obtained from subtracting the non-magnetic contribution. c The magnetic entropy (Smag) versus temperature at 0 T obtained by integrating Cmag/T. The horizontal red dashed line shows the value of Rln2.
