Abstract In this paper, we investigate the thermodynamic properties andgeometries of phantom (A) dS F (R) black holes in the presence ofrecently proposed generalized entropy. For this purpose, we evaluatethe heat capacity, Helmholtz free energy, Gibbs free energy, compressibility factor Z and the isothermal compressibility (T) for analyzing the local and global stability of thisblack hole. We also analyze the thermal geometries of this blackhole, which provide useful insights. Furthermore, we presentisotherms on the P-V diagram illustrating phase behavior. It isinteresting to mention here that generalized entropy providesignificant and useful impact on the results of thermal analysis ofaforementioned black holes.
