Query: Magnetic black holes with generalized ModMax model of nonlinear
  electrodynamics   Recently Bandos, Lechner, Sorokin, and Townsend [Phys. Rev. D \textbf{102},
121703 (2020)] proposed Modified Maxwell (ModMax) model of nonlinear
duality-invariant conformal electrodynamics. Here, Generalized ModMax
(GenModMax) model of nonlinear electrodynamics coupled to general relativity is
studied. The metric and mass functions, and their asymptotic as
$r\rightarrow\infty$ and $r\rightarrow 0$ of a magnetic black hole are
obtained. Corrections to the Reissner--Nordstr\"{o}m solution are found and we
show that for some model parameters the black hole is regular. The Hawking
temperature and heat capacity of black holes are calculated and phase
transitions are investigated. We demonstrate that black holes are not stable
for certain model parameters.
