  This paper is an informal review of the present status of the computational
studies of models for manganites that recently reported the existence of phase
separation at low temperatures (S. Yunoki et al., Phys. Rev. Lett. 80, 845
(1998) and cond-mat/9807149). Results for both the one-orbital and two-orbital
models, the latter with Jahn-Teller phonons, are included. A large list of
experimental results discussed in the paper are compatible with the existence
of charge-inhomogeneities in the manganites, which may be an important
ingredient for the explanation of the CMR effect in these compounds.
