Figure 4
(a) Specific heat C_p (solid circles) of Gd₄Ga₂O₉ under zero field in the temperature range from 0.40 to 30 K. The dash–dotted line represents the phonon contribution by the Debye function fit (see the text for details). (b) $[C_{\rm mag}/T]$ (left axis) and the magnetic entropy $[S_{\rm mag}]$ (right axis) calculated from $[C_{\rm mag}/T]$ curves of Gd₄Ga₂O₉ versus temperature. The theoretical Gd³⁺ magnetic ion contribution to the magnetic entropy is indicated by the dotted line positioned at R ln8.
