摘要：This paper studies changes in the relationship between magnetic properties of La5/8Ca3/8Mn1-xCoxO3 (x <= 0.3) system and temperature and magnetic field. By the lattice structure of the sample when x=0.3 varies with temperature analysis that, related changes of lattice structure also occurred in the magnetic transition region. The difference of lattice parameter is increased, orthogonal O' phase substitute orthogonal O. We speculate that spin-state transitions may be appear in this interval. At low temperature of x=0.3 sample, the behavior of AFM sample should coexist with the CG, eg itinerant electron reduce, resistance increase and drastically reduce conductivity.
