Physics of the Dark Universe 42 (2023) 101299 In this paper, we study the thermodynamic features of a non-linear
magnetic-charged AdS black hole surrounded by quintessence, in the background
of perfect fluid dark matter(PFDM). After having constructed the corresponding
metric, we analyse the structure of the horizon. We find that the existence of
inner or outer horizon are constrained by the presence of dark matter.
Afterwards, we put out the mass and the temperature of the black hole, in order
to get its entropy. Subsequently, we find the expression of the pressure which
leads us to get the table of critical values and the isothermal diagram.
Especially, we find that the critical values of the temperature and the
pressure increase as the dark matter parameter increases. Also, analysing the
isothermal diagram, we observe a van der Waals-like behaviour remarked by the
presence of a first-order phase transition when we cross the critical
temperature. Additionally, we compute and plot the heat capacity and the
Hessian matrix of the black hole mass. For the heat capacity, we find that a
second-order phase transition occurs, leading the black hole to move from
stable phase to unstable one. Furthermore, it comes out that this phase
transition point is shifted towards higher values of the horizon radius, as we
decrease the dark matter density and increase the quintessence density.
