Crystal growth and magnetic properties of the double perovskites R2MnNiO6 (R=Pr, Sm and Ho) by a hydrothermal route

Functional properties of Sm2NiMnO6 multiferroic ceramics prepared by spark plasma sintering

“…The XRD pattern shows a high degree of crystallization. The main diffraction peaks of the XRD profile are in good agreement with the XRD data already reported in the literature for the double perovskite oxides systems [17,18,20,21] and are usually indexed to the monoclinic structure with P2 1 /n, space group.…”

“…3(b, c)) display clear lattice fringes that further confirm a high crystallinity level of the material. The characteristic distances, accurately measured on the power spectrum ( [18,20,21]. Booth et al [18] explained this downturn in the magnetization at lowest temperatures for the Sm 2 NiMnO 6 and Nd 2 NiMnO 6 systems as due to the presence of magnetocrystalline anisotropy induced by the spin-orbit coupling of the Mn-Ni network to rare earth.…”

“…Lin et al [15] reported that the giant dielectric characteristics are due to the charge ordering of Ni 2+ and Mn 4+ . Consequently, the debate related to the Ni-O-Mn electronic interaction offer to the [18,[20][21][22] and one presents density functional theory (DFT) calculation of the electronic band structure in Sm 2 NiMnO 6 double perovskite [23]. Booth et al [18] reported structural and functional properties of different oxides of R 2 NiMnO 6 type, including the R=Sm system produced by solid state reaction.…”

“…Recently, Zhang et.al. [20], gave data on the crystal growth and magnetic properties of Sm 2 NiMnO 6 oxides synthesized by hydrothermal method, for which a ferromagnetic character was found at T=5K. More recently, Yang et al [21] determined the magnetic and dielectric characteristics together with the crystal structure of Ln 2 NiMnO 6 (where Ln=Nd and Sm) and…”

Structural characteristics, magnetic properties of Re2NiMnO6 (Re=La, Pr, Nd, Sm, Y) thin films on (001) LaAlO3 by simple polymer assisted deposition

“…The perovskite family shows a gradual structural change as A-site ionic radius decreases. Besides, their properties also change noticeably with the substitution of La 3+ by a rare-earth element with smaller ionic radius [19][20][21][22][23], which can be attributed to the changes of the B(B′)-O bond length, B-O-B′ bond angles, and bond exchange interactions. For instance, smaller lanthanide substitution for La shrinks the Cu-O bond length and increases the CuO 2 layer buckling in Ln 2 CuSnO 6 (Ln = La, Pr, Nd, and Sm) system [24].…”
