(a) Temperature dependences of total heat capacity under different magnetic fields in YbMgGaO4 and LuMgGaO4. The dashed curve denotes the Debye heat capacity. (b) Temperature dependences of magnetic heat capacity under different magnetic fields in YbMgGaO4. The colored dash lines show the power law fits to the low-T magnetic heat capacities. (c) Magnetic heat capacity vs. 1/T in YbMgGaO4. The red dash line shows the gapped spectral function fit to the low-T magnetic heat capacities under 0 T. Inset: fitted power exponent γ. (d) Temperature dependences of integral magnetic entropy under different magnetic fields in YbMgGaO4.
