We study the thermodynamic and high-magnetic-field properties of the magnetic insulator ${\mathrm{Ba}}_{5}{\mathrm{CuIr}}_{3}{\mathrm{O}}_{12}$, which shows no magnetic order down to 2 K, consistent with a spin-liquid ground state. While the temperature dependence of the magnetic susceptibility and the specific heat shows only weak antiferromagnetic correlations, we find that the magnetization does not saturate up to a field of 59 T, leading to an apparent contradiction. We demonstrate that the…
