论文摘要
在这封信中，我们提出了具有非线性电动力学指数模型的确切球形对称和磁性的黑洞溶液[S.克鲁格洛夫（Kruglov），Annals Phys。 378，59-70（2017）]在4D爱因斯坦 - 加斯 - 邦网（EGB）重力的背景下。我们表明，在GB耦合系数$α\ rightarrow 0 $和非线性参数$β\ 0 $的限制的限制中，我们的$ - $ ve分支减少到GR中Einstein-Maxwell Gravity的磁性黑洞。此外，我们研究了黑洞几何形状的嵌入图和热力学特性，例如鹰温度和黑洞溶液的热容量。
In this letter we present an exact spherically symmetric and magnetically charged black hole solution with exponential model of nonlinear electrodynamics [S. Kruglov, Annals Phys. 378, 59-70 (2017)] in the context of 4D Einstein-Gauss-Bonnet (EGB) gravity. We show that our $-$ve branch, in the limit of GB coupling coefficient $α\rightarrow 0$ and the nonlinear parameter $β\to 0$, reduces to the magnetically charged black hole of Einstein-Maxwell gravity in GR. In addition we study the embedding diagram of the black hole geometry and the thermodynamic properties such as the Hawking temperature and the heat capacity of our black hole solution.
