(color online) (a) Temperature dependence of the magnetic specific heat of YbMgGaO₄ under different magnetic fields. Dashed lines indicate power-law fits to the low-temperature data. From Ref. [43]. (b) Magnetic specific heat of YbZnGaO₄ measured under zero and 9-T fields. Solid lines are fits to the data. From Ref. [51].
