Comparative study of heterogeneous magnetic state above T C in La 0.82Sr 0.18CoO 3 cobaltite and La 0.83Sr 0.17MnO 3 manganite [link]Paper  doi  abstract   bibtex   
The magnetic, transport and structural properties are studied for La 0.83Sr 0.17MnO 3 and La 0.82Sr 0.18CoO 3 single crystals with nearly the same doping and the metallic ground state. Their comparisons have shown that ferromagnetic clusters originate in the paramagnetic matrix below >T C in both samples and exhibit similar properties. This suggests the possible universality of such phenomena in doped mixed-valence oxides of transition metals with the perovskite-type structure. The cluster density increases on cooling and plays an important role on the physical properties of these systems. The differences in cluster evolutions and scenarios of their insulator-metal transitions are related to different magnetic behaviors of the matrixes in these crystals that is mainly due to distinct spin states of the Mn 3 and Co 3 ions. © 2012 Elsevier B.V.
