  In this work, we investigated the existence of compacton-like configuration
in the O(3)-sigma model. We consider a minimally coupled O(3)-sigma model with
a gauge field governed by a generalized Chern-Simons term. Contrary to that
established in the literature, we impose a new set of boundary conditions and,
we find solutions of the variable fields and the respective energy density in
the Bogomol'nyi limit. On the other hand, the introduction of a parameter
$\omega$ in the Chern-Simons term can be adjusted to leads to finite-energy
solutions of the model. Moreover, compact-like structures were studied with the
evolution of this $\omega$ generalized Chern-Simons term.
