In this work a static spherically symmetric black hole's solution within the Einstein-Maxwell-Yang-Mills-dilaton theory is derived. The obtained solution is examined, in particular, we have calculated the Kretschmann scalar which allowed us to characterize singularity points. Using the obtained black hole's solution we have studied its thermodynamics. Namely, the temperature was calculated, the first law was written, and the heat capacity was studied. The extended thermodynamics approach is utilized to obtain the equation of state. Within the extended thermodynamics the Gibbs free energy is derived and investigated. The analysis of the Gibbs free energy shows that below the critical temperature besides the first order phase transition in addition the zeroth order phase transition occurs, what is typical for other types of black holes with dilaton fields. Finally, we have shown that the critical exponents take the same values as for other types of the dilaton black holes.

We consider a model where massive static spherically symmetric black hole, in the presence of power-Yang-Mills source, is surrounded by a dark fluid with non-linear equation of state. In this set up we construct a new class of magnetized Lovelock black hole solutions of the gravitational field equations. In particular, we work out the metric functions in both D-dimensional massive Einstein and massive Gauss-Bonnet gravities. We study thermodynamics of these black holes also and show that the mass and associated thermodynamic quantities like Hawking temperature and heat capacity depend on parameters of the dark fluid and the power-Yang-Mills magnetic source. We note that the entropy does not satisfy the area law in Gauss-Bonnet and higher order Lovelock black holes. Furthermore, phase transitions of black holes in each case are also discussed.

“…The solution obtained with the use of these NLED models are singularity-free black hole solutions which asymptotically behave as the Reisnner-Nordström (RN) black hole [33,34]. There are alot of nonlinearly charged black hole solutions in ETG and other modified gravities coupled to NLED have been found in literature [65][66][67][68][69][70][71][72][73]. Moreover, instead of dark energy, non-linear electromagnetic fields are introduced to explain the inflation period in initial times where universe was born [74,75].…”

A recently proposed model for double-Logarithmic electrodynamics [25] has been coupled to Lovelock gravity and the nonlinearly magnetized black holes are investigated. In this set up, the Lovelock polynomial which generates magnetized topological Lovelock black hole solution has been constructed and the associated thermodynamical quantities such as mass, entropy, Hawking temperature and heat capacity are computed. The black hole solutions in Einstein and Gauss-Bonnet gravities are also derived in this context of double-Logarithmic electrodynamics and gravity. Each of the associated thermodynamical quantities have been plotted and the regions corresponding to thermal phase transitions and thermodynamical stability/instability are also pointed out.
