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 .
