  We consider particlelike solutions to supergravity based on the Kerr-Newman
black hole (BH) solution. The BH singularity is regularized by means of a phase
transition to a new vacuum state near the core region confining a dual gauge
field. Supersymmetric BPS-saturated domain wall model is suggested which can
provide this phase transition and formation the stable charged superconducting
core. For spinning particle the core takes the form of thin, relativistically
rotaiting disk.
