Journal ArticleDOI
Hydrothermal synthesis of (00l) epitaxial BiFeO3 films on SrTiO3 substrate
A. Huang,Albertus D. Handoko,Gregory K. L. Goh,Pramoda K. Pallathadka,Santiranjan Shannigrahi +4 more
TL;DR: In this article, it was found that the morphology evolution of the (001)PC-oriented BFO films over time and temperature involve unique dissolution-reprecipitation reactions, whereby initial large sparse islands dissolve, and re-precipitate into dense mosaic-like structures that further grow vertically, resembling those of terrace-like structure.
Journal ArticleDOI
Effects of WO3 dopant on the structure and electrical properties of Pb0.97La0.03(Zr0.52Ti0.48)O3 thin films
Santiranjan Shannigrahi,Kui Yao +1 more
TL;DR: In this article, a defect chemistry mechanism indicating the reduction of oxygen vacancies by the substitution of W for Ti at different doping concentrations has been proposed, which shows that WO3 dopant plays a significant role on the structure and electrical properties of the PLWZT films.
Journal ArticleDOI
Complex permittivity, permeability, magnetic and microwave absorbing properties of Ni2+ substituted mechanically milled U-type hexaferrites
Sandeep Kumar,Sandeep Kumar,Divya Prakash Dubey,Santiranjan Shannigrahi,Ratnamala Chatterjee +4 more
TL;DR: In this article, a two-stage high energy mechanical jet milling was performed on Ni2+ substituted U-type hexaferrite, in steps of 0.25 and 0.75, to reduce the grain sizes down to nanoscale.
Journal ArticleDOI
General one-step self-assembly of isostructural intermetallic Co(II)(3)Ln(III) cubane aggregates.
TL;DR: Single-crystal X-ray diffraction analysis revealed that the new family of Co/rare-earth intermetallic cubane aggregates synthesized by self-assembly are remarkably isostructural in showing a common [Co3Ln] core.
Journal ArticleDOI
Impedance spectroscopy, electronic structure and X-ray photoelectron spectroscopy studies of Pb(Fe1/2Nb1/2)O3
TL;DR: In this paper, the authors used X-ray photoemission spectroscopy (XPS) to study the electrical properties of lead iron niobate, Pb(Fe1/2Nb1/1)/2)O3 in the frequency range from 100 Hz to 1 MHz and in the temperature range from 203 to 363 K. The complex impedance plane plot shows that the relaxation (conduction) mechanism in PFN is purely a bulk effect arising from the semiconductive grains.
