Structural, magnetic and electrical properties of La0.67Pb0.33Mn1−xCoxO3 (0≤x≤0.3)

Effect of Co substitution on magnetocaloric effect in La0.67Pb0.33Mn1−xCoxO3 (0.15≤x≤0.3)

“…X-ray analysis X-ray diffraction (XRD) studies for La 0.67 Pb 0.33 Mn 1−x Co x O 3 (0.15 ≤ x ≤ 0.3) manganites perovskite in our pervious investigation [7] indicate that all the samples are single phase without detectable secondary phase within the sensitivity limits of the experiment (a few percent). The diffraction peaks are indexed with respect to the rhombohedral perovskite-type structure with a space group of R3c.…”

Synthetic Methods for Perovskite Materials; Structure and Morphology

“…However, some reduction in the particle size was observed in the case of La 0.67 Pb 0.33 Mn 1-x Co x O 3 (x= 0 and 0.3) compounds, which were also prepared by the ceramic route (Dhahri et al, 2010). The present observation of a reduction in the particle size of the Nd 0.8 Sr 0.2 (Mn 1-x Co x )O 3 phases in one of the methods but not in the other would point towards the synthesis method as the responsible for this effect, rather than the amount of cobalt.…”

Critical Behavior of Ti Doping La0.57Nd0.1Pb0.33Mn1−x Ti x O3 Perovskite System

“…Therefore, the double exchange interaction is weakened with increasing Ti doping in the samples. The reduction of T C should be related to the dilution of the Mn sublattice, i.e., the reduction of Mn 4+ content results into dominance of ferromagnetic super exchange interaction between Mn cations [16,17]. Figure 3 shows the temperature dependence of the inverse magnetic susceptibility χ m deduced from M(T ) at 500 Oe for all samples.…”
