  In equilibrium, at finite temperature below and above the deconfining phase
transition, we have generated lattice SU(2) gauge fields and have exposed them
to smearing in order to investigate the emerging clusters of topological
charge. Analysing in addition the monopole clusters according to the maximally
Abelian gauge, we have been able to characterize part of the topological
clusters to correspond either to non-static calorons or static dyons in the
context of Kraan-van Baal caloron solutions with non-trivial holonomy. We show
that the relative abundance of these calorons and dyons is changing with
temperature and offer an interpretation as dissociation of calorons into dyons
with increasing temperature. The profile of the Polyakov loop inside the
topological clusters and the (model-dependent) accumulated topological cluster
charges support this interpretation. Above the deconfining phase transition
light dyons (according to Kraan-van Baal caloron solutions with almost trivial
holonomy) become the most abundant topological objects. They are presumably
responsible for the magnetic confinement in the deconfined phase.
