In this Letter, we presented a class of rotating solutions in Gauss–Bonnet gravity in the presence of a nonlinear electromagnetic
field. These solutions are not real for the whole spacetime and so, by a suitable transformation, we presented the real solutions. We
found that these solutions reduce to the solutions of Gauss–Bonnet–Maxwell gravity as s = 1, and reduce to those of Einstein–power
Maxwell invariant gravity as α vanishes. Then we studied the kind of singularity and found that, in contrast to the Einstein–power
Maxwell invariant gravity, for all values of nonlinear parameter, we can always choose the suitable parameters to have timelike singularity.
Also, we found that as in the case of rotating black brane solutions of Einstein-power Maxwell invariant gravity, for 0 < s < 12
, the
asymptotic dominant term of metric function f (r) is charge term, and the presented solutions are not asymptotically AdS, but for the
cases s 12
, the asymptotic behavior of rotating Einstein–nonlinear Maxwell field solutions are the same as linear AdS case. In the
other word, we found that the Gauss–Bonnet does not effect on the asymptotic behavior of the solutions. Then, we applied counterterm
method to the solutions with flat boundary at r = constant and t = constant, and calculated the finite action and their conserved and
thermodynamic quantities. The physical properties of the black brane such as the temperature, the angular velocity, the electric charge
and the potential have been computed. We found that the conserved quantities of the black brane do not depend on the Gauss–Bonnet
parameter α. Consequently, we obtained the entropy of the black brane through the use of Gibbs–Duhem relation and found that it obeys
the area law of entropy. Then, we obtained a Smarr-type formula for the mass as a function of the extensive parameters S, J and Q , and
calculated the intensive parameters T , Ω and Φ. We also showed that the conserved and thermodynamic quantities satisfy the first law
of thermodynamics.
