Effect of octahedral tilting on antiferroelectric phase stabilization in (1-x)NaNbO3-xCdTiO3ceramics

Gyan, D.S.; Sharma, P.; Dwivedi, A. (Institute of Physics Publishing, 2020-08-12)

In the present work, a unique case for the stabilization of the antiferroelectric phase in NaNbO3 has been presented, where the desired results were obtained in spite of it defying the set pattern predicted by researchers ...
Enhancement of thermoelectric power factor by inducing octahedral ordering in La2-xSrxCoFe O6 double perovskites

Tanwar, K.; Gyan, D.S.; Bhattacharya, S.; Vitta, S.; Dwivedi, A.; Maiti, T. (American Physical Society, 2019-05-14)

Among the various oxide thermoelectric materials, double perovskites provide more flexibility to maneuver interdependent thermoelectric parameters to achieve enhanced thermoelectric figure of merit (ZT), as octahedral ...
Investigation of crystal structure, microstructure and low temperature magnetic behavior of Ce4+ and Zn2+ co-doped barium hexaferrites (BaFe12O19)

Tanwar, K.; Gyan, D.S.; Gupta, P.; Pandey, S.; Omparkash; Kumar, D. (Royal Society of Chemistry, 2018)

Ce4+ and Zn2+ co-doped barium hexaferrites (BFO) have been synthesized via a citrate-nitrate autocombustion route. Phase purity has been confirmed by high resolution (HR) powder X-ray diffraction analysis. Rietveld refinement ...
