  In nonlinear electrodynamics coupled to general relativity and satisfying the
weak energy condition, a spherically symmetric electrically charged
electrovacuum soliton has obligatory de Sitter center in which the electric
field vanishes while the energy density of electromagnetic vacuum achieves its
maximal value. De Sitter vacuum supplies a particle with the finite positive
electromagnetic mass related to breaking of space-time symmetry from the de
Sitter group in the origin. By the G\"urses-G\"ursey algorithm based on the
Newman-Trautman technique it is transformed into a spinning electrovacuum
soliton asymptotically Kerr-Newman for a distant observer. De Sitter center
becomes de Sitter equatorial disk which has both perfect conductor and ideal
diamagnetic properties. The interior de Sitter vacuum disk displays
superconducting behavior within a single spinning soliton. This behavior found
for an arbitrary nonlinear lagrangian ${\cal L}(F)$, is generic for the class
of regular spinning electrovacuum solutions describing both black holes and
particle-like structures.
