Understand

In the presence of external, linear / nonlinear electromagnetic fields we integrate f(R) \sim R+2{\alpha}\surd(R+const.) gravity equations.

In contrast to their Einsteinian cousins the obtained black holes are non-asymptotically flat with a deficit angle.
In proper limits we obtain from our general solution the global monopole solution in f(R) gravity.
The scale symmetry breaking term adopted as the nonlinear electromagnetic source adjusts the sign of the mass of the resulting black hole to be physical.
