Magnetic black holes in AdS space with nonlinear electrodynamics, extended phase space thermodynamics and Joule–Thomson expansion

This paper studies thermodynamics of magnetically charged black holes in Anti-de Sitter space an extended phase space. The cosmological constant is considered as a pressure and the hole mass treated chemical enthalpy. similar to Van der Walls liquid–gas thermodynamics. Quantities conjugated nonlinear electrodynamics parameter magnetic charge are obtained. first law generalized Smarr relation take place. We investigate critical behavior Joule–Thomson expansion. Gibbs free energy, coefficient inversion temperature calculated.
