The Bi2Mn0.1V0.9O5.35-δ (BIMNVOX.10) thin films have been successfully deposited on the LaNiO3(LNO)/Si (100) substrates by chemical solution deposition process. The phases, morphology and electrical properties of samples have been studied. The BIMNVOX.10 films show a (00l)-preferred orientation and have a homogeneous distribution of grains. A low frequency dielectric dispersion observed in the films may be originated from the short distant diffusion of oxygen vacancies. The Cole-Cole plots of dielectric constant for the BIMNVOX.10 films appear semicircular arc with the center off the x-axis and deviate from the ideal mono-dispersive Debye model. The frequency dependent of ac conductivity for BIMNVOX.10 films follows the Joscher’s power law, mainly contributed to the grain resistivity and predicts the nature of an oxygen vacancies conduction process. The complex impedance spectra reveal that electrical process arises due to contribution from the grain interior and grain boundary effects.

“…The doped Mn 4+ was reduced to Mn 3+ , and when the temperature was higher than 650 C, it was reduced to Mn 2+ , which was due to the release of O2. Alga 21 believed that the solute was the γ phase in the range of 0.075 ≤x≤0.25, Mn 3+ in the range of 0.075≤x≤0.10, and Mn 3+ /Mn 4+ in the range of 0.15≤x≤0.25. Mn 4+ increased with an increase in MnO2, and the highest oxygen ion conductivity was obtained when the doping amount of MnO2 was x = 0.1.…”

The emerging field of matermetallomics refers to all research activities aimed at the clarification of the role and function of metallic elements in materials. This paper discusses the concept of matermetallomics and the related analytical techniques used for probing the interactions between structure-activity relationships. The main object of matermetallomics research is metallic elements in materials, and includes the significance and contributions to materials science. This paper also introduces the analytical approaches used in matermetallomics, which includes the techniques of imaging, spectroscopic, X-ray-based, ion beam, MS-based and atomic spectrometry. Recently, this technology has been successfully applied to some novel materials, such as energy materials, gas separation materials, alloy materials, catalytic materials, polymer materials and others for specific applications. 2-7 Studies have shown that the composition as genes of materials is an important link in the chain of processing, structure, properties, and performance, which is worthy of attention and discussion.

“…Hence, numerous solid solutions had been prepared by substituting vanadium (V 5+ ) by other metallic cations. These solid solutions constitute a family of compounds known by the acronym BiMeVOX (Me= Co, Cu, Mn, …) [11][12][13][14][15][16]. Generally, the α, β and γ forms are progressively stabilized by increasing the substitution rate.…”
