Magnetization and specific heat data as well as the CEF energy levels confirm that the ground state is characterized by the low-lying Kramers' doublet of Yb$^{3+}$ with effective spin-1/2 ($J_{\\rm eff} = 1/2$). A small Curie-Weiss temperature and scaling of magnetic isotherms corroborate very weak magnetic correlations among $J_{\\rm eff} = 1/2$ spins.
