Abstract :
In this paper, we obtain a new class of (n+1)-dimensional magnetic brane
solutions of quasi-topological gravity in the presence of exponential and logarithmic
nonlinear electrodynamics by a spinning magnetic branes with one or more rotation
parameters. For the spinning brane, the brane has a net electric charge, when one
or more rotation are non zero, and also this electric charge is proportional to the
magnitude of the rotation parameter. However, when all the rotation parameters are
zero (static brane), the electric eld vanishes and the brane has no net electric charge.
In the class of solutions, we have a spacetime with an angular magnetic eld. These
solutions are horizonless and have no curvature, but there is a conic singularity with
a decit angle. In addition, these two forms of nonlinear electrodynamics theory have
the same behaviors for the obtained solutions. Finally, we use the counterterm method
and compute conserved quantities of these spacetimes.
