    TA non-uniform magnetic state in the perovskite system LaMn0.6Co0.4O3 has been studied by magnetometric methods.Two ferromagnetic (FM) critical temperatures are observed.The first one at Tc=217 K is ascribed to the onset of FM state in the Mn4+/Co2+-ordered domains(phase 1), while the disordered regions containing Mn4+, Mn3+,Co3+ and Co2+ valence states (phase 2) remain in the paramagnetic state. Below Tc=147 K a long-range FM arrangement develops also in certain part of phase 2, but the major part of phase 2 is formed by polydisperse FM clusters.
