Abstract
For expanding horizon of multifunctional materials, synthesis of Pr3Ni2NbO9 in the series of modified double perovskite in single phase polycrystalline form is reported here for the first time to best of our knowledge. The phase purity has been confirmed by X-ray diffraction and neutron diffraction performed under ambient conditions where conclusions were drawn on basis of reports of iso-structural double perovskite compound like La3Ni2TaO9, recently studied by some of us. Field Emission-Scanning electron microscope (FE-SEM), energy dispersive x-ray spectroscopy (EDS) and x-ray photoelectron spectroscopy (XPS) has been carried out, XPS results suggest that constituent elements are not in mixed valence state. The temperature dependent DC magnetization study indicates spontaneous magnetic ordering at ∼28 K and the AC susceptibility study rule out glassy behavior. The neutron diffraction study at 2 K does not show any signature of magnetic ordering. This has been further examined by specific heat and dielectric study for further understand the physical properties. We emphasis that such behavior needs to be examined in more details by theoretical and advanced experimental characterization techniques to probe magnetism at local level.
期刊介绍:
Ceramics International covers the science of advanced ceramic materials. The journal encourages contributions that demonstrate how an understanding of the basic chemical and physical phenomena may direct materials design and stimulate ideas for new or improved processing techniques, in order to obtain materials with desired structural features and properties.
Ceramics International covers oxide and non-oxide ceramics, functional glasses, glass ceramics, amorphous inorganic non-metallic materials (and their combinations with metal and organic materials), in the form of particulates, dense or porous bodies, thin/thick films and laminated, graded and composite structures. Process related topics such as ceramic-ceramic joints or joining ceramics with dissimilar materials, as well as surface finishing and conditioning are also covered. Besides traditional processing techniques, manufacturing routes of interest include innovative procedures benefiting from externally applied stresses, electromagnetic fields and energetic beams, as well as top-down and self-assembly nanotechnology approaches. In addition, the journal welcomes submissions on bio-inspired and bio-enabled materials designs, experimentally validated multi scale modelling and simulation for materials design, and the use of the most advanced chemical and physical characterization techniques of structure, properties and behaviour.
Technologically relevant low-dimensional systems are a particular focus of Ceramics International. These include 0, 1 and 2-D nanomaterials (also covering CNTs, graphene and related materials, and diamond-like carbons), their nanocomposites, as well as nano-hybrids and hierarchical multifunctional nanostructures that might integrate molecular, biological and electronic components.
