  We consider electroweak baryogenesis mediated by embedded domain walls.
Embedded domain walls originating from a symmetry breaking phase transition are
stabilized by thermal plasma effects, so that the electroweak symmetry is
unbroken in their cores. For this reason, the cosmological evolution of such
domain walls can generate a sufficiently large baryon asymmetry, irrespective
of the order of the electroweak phase transition. For embedded domain walls,
the condition that the energy of the universe not be dominated by the energy of
the domain walls is relaxed significantly, and it is shown to be compatible
with our scenario of electroweak baryogenesis.
