The magnetic structure of the doped perovskite manganites
and
at a temperature of 10
has been investigated by using the
decoration technique in a wide region of external magnetic fields
(up to 1000
). We observe the multidomain ferromagnetic
state in
and the coexistence of the
ferro- and nonmagnetic phases in
. The dependence of the
structure on an external magnetic field has been investigated in
.
