(a) Temperature versus the event horizon radius \(r_h\). (b) Gibbs free energy-temperature diagram. (c) Landau function L in terms of the parameter X for different temperatures. (d) Landau function L in terms of the black hole volume V. (e) \(\gamma\)-function in terms of the black hole volume V. (f) On-shell Gibbs free energy \(\tilde{G}\) as a function of temperature T. The arrows indicate the evolution of the temperature and the pink region indicates where the thermal radiation phase is the global stable phase \((T<T_{HP})\) with \(Q = 0.010026\), \(l=1\), and \(b=3.5\).
