ChemInform Abstract: Functional Properties of Sm2NiMnO6 Multiferroic Ceramics Prepared by Spark Plasma Sintering.

In the present work, it was reported for the first time the new synthesis of Sm2NiMnO6 double perovskite oxides by sol–gel auto-combustion method. The Rietveld analysis of the X-ray ceramics diffraction pattern recorded at room temperature for Sm2NiMnO6 ceramics sintered at 1000 °C/5 min from powders obtained at 700 °C/7 h confirm the formation of the double perovskite with a monoclinic structure and the space group P21/n. The HRTEM analysis shows clear lattice fringes that confirm a high crystallinity level of the material corresponding to the monoclinic structure. The non-linear dielectric character was checked for the first time in Sm2NiMnO6 double perovskite and the results reveals a strong nonlinearity and a small hysteretic behaviour. The present structural, magnetic and dielectric data make the Sm2NiMnO6 system due to its multiferroic character a promising candidate to different modern electronic devices applications.
