It has a<br /><br />magnetic charge which makes central region of the black hole<br /><br />metric to be AdS spacetime and so become non singular.<br /><br />\textcolor[rgb]{0.00,0.00,1.00}{Thus we not need to use an<br /><br />additional cosmological parameter coming from ADS/CFT<br /><br />correspondence for production of pressure coordinate in the black<br /><br />hole equation of state. Form this point of view our work is a new<br /><br />approach versus to conventional methods which are addressed in the<br /><br />references of this paper. However we will see important behavior<br /><br />of parameters of this modified ABG black hole on possibility of<br /><br />being of JT adiabatic expansion.} This black hole is characterized<br /><br />by five parameters including mass $m$, magnetic charge $q$, and<br /><br />three \textcolor[rgb]{0.00,0.00,1.00}{other} parameters related to<br /><br />form of used nonlinear electromagnetic interaction fields.<br /><br />\textcolor[rgb]{0.00,0.00,1.00}{Inversion points are in fact a<br /><br />particular T-P curve at constant enthalpy and it separates cooling<br /><br />and heating phase of the modified AdS ABG black hole.} https://ijaa.du.ac.ir/article_336_2e61986f0ed47bbfb13ce1b4b29cd3b2.pdf
