The magnetization density has been studied by polarized neutron scattering
in the ferromagnetic 
manganite at 20 K and at 290 K, close to
the Curie point. A weak preponderance of 
Mn wave functions is observed,
as well as a positive polarization on oxygen. At low temperature, the density
on Mn corresponds to a well-localized moment of 
and a more diffuse
component. Heating the sample leads to a non-uniform renormalization of the
magnetization density.
