AbstractThe series of perovskite rare-earth (RE) doped cobaltites (RE)CoO3 (RE = La -Dy) was prepared by microwave-assisted synthesis. The crystal structure undergoes a change of symmetry depending on the size of the RE cation. LaCoO3 is rhombohedral, S.G. , while for the rest of the RE series (Pr -Dy) the symmetry is orthorhombic, S.G. Pnma (No. 62). The crystal structure obtained by X-Ray diffraction was confirmed by high resolution transmission electron microscopy, which yielded a good match between experimental and simulated images. It is further shown that the well-known magnetism in LaCoO3, which involves a thermally induced Co 3+ (d 6 ) low spin to intermediate or high spin state transition, is strongly modified by RE-doping and a rich variety of magnetic order has been detected across the series.

Effect of Multiplicity Fluctuation in Cobalt Ions on Crystal Structure, Magnetic and Electrical Properties of NdCoO3 and SmCoO3

“…The temperature dependence of the magnetic susceptibility of RCoO 3 is determined by the magnetization of rare-earth ions and the additional paramagnetic contribution induced by the thermally excited magnetic terms of Co 3+ ions. The obtained experimental data are in good agreement with similar studies in recently published works [44,45].…”

General Strategy for Rapid Production of Low-Dimensional All-Inorganic CsPbBr3 Perovskite Nanocrystals with Controlled Dimensionalities and Sizes

“…Microwave (MW) irradiation is recognized as one of the most popular and versatile strategies for fabricating materials in nearly all systems, − owing to the following unique advantages: , (i) homogeneous heating, (ii) high heating rate, (iii) selective activation of the target precursor, (iv) high reproducibility, (v) convenient and near-continuous process, and (vi) rapid production and high throughput. To the best of our knowledge, until most recently, just a few works have shed light on the synthesis of CsPbX 3 perovskites , based on the MW technique.…”

Structural, magnetic, electronic, and dilatation properties of the ordered solid solutions Ln0.2Sr0.8CoO3-δ (Ln = Sm, Gd, Dy) with the same oxygen nonstoichiometry index δ

“…For Sm 0.2 Sr 0.8 CoO 2.63 in both ZFC and FC measurement modes, an increase in the susceptibility at low temperatures was not noted (Fig. 4a), which is probably due to the small effective magnetic moment of the Sm 3+ ions (µ theor = 1.55 µ B ), although for LnCoO 3 (Ln = Sm, Gd, Dy) compounds [29,30], the increase in the susceptibility at low temperatures is characteristic of all compositions.…”
