High pressure synthesis, structure, and multiferroic properties of two perovskite compounds Y2FeMnO6 and Y2CrMnO6.
High purity crystals of Y2FeMnO6 (YFMO) and Y2CrMnO6 (YCMO) have been synthesized for the first time using a flux method under a high temperature of 1573 K and high pressure of 6 GPa. Both YFMO and YCMO have orthorhombic structures in space group Pnma. The temperature-dependent magnetization and the nonlinear M-H hysteresis loops of both materials indicate that an antiferromagnetic transition o...
متن کاملThe Effect of Europium Doping on the Structural and Magnetic Properties of GdMnO3 Multiferroic Ceramics
Single phase Eu doped GdMnO3 ceramics were prepared using solid state reaction route. Several different characterization techniques were used to investigate the structural and magnetic properties of the samples, including X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDX) and Vibrating Sample Magnetometer (VSM). All samples indicated single p...
متن کاملEXPERIMENTAL AND THEORETICAL STUDY OF THE STRUCTURAL, MAGNETIC AND ELECTRONIC PROPERTIES OF THE BA2GDSBO6 PEROVSKITE
In this work the procedure to the synthesis of Ba2GdSbO6 complex perovskite by the solid-state reaction method is reported. Theoretically a study of the crystalline and electronic structure was performed into the framework of the Density Functional Theory (DFT). The most stable structure is obtained to be a rhombohedral perovskite with a lattice constant a=6,0840 Å. Due the occurren...
متن کاملPerovskite oxide superlattices: Magnetotransport and magnetic properties.
We have fabricated perovskite superlattices consisting of two ferromagnetic metallic oxides: La0.67Ca0.33MnO3 ~LCMO! and SrRuO3 ~SRO!. We have investigated the magnetotransport and magnetic properties of a series of samples, in which the layer thickness of LCMO is fixed and that of SRO varied from 0 to 20 unit cells. The magnetoresistance ratio in a superlattice can be increased by a factor of ...
متن کاملStructure-Controllable Synthesis of Multiferroic YFeO3 Nanopowders and Their Optical and Magnetic Properties
Phase-pure hexagonal and orthorhombic YFeO₃ nanopowders are synthesized by low-temperature solid-state reaction along with Zr doping. The obtained powders are characterized by X-ray diffraction, field emission scanning electron microscopy, and physical property measurements. The hexagonal YFeO₃ exhibits a narrower optical band gap in comparison to the orthorhombic one, while the orthorhombic YF...
