Anita Verma, Arun Kumar Yadav, Nasima Khatun +7
The structural, dielectric and ferroelectric properties of lead-free (Na0.5-xKxBi0.5-xLax)TiO3 powders synthesized by sol-gel self-combustion method were investigated. Rietveld ref…
(Pb1-xBix)(Ti1-xMnx)O3: Competing mechanism of Tetragonal-Cubic phase on A/B site modifications
Arun Kumar Yadav, Anita Verma, Birender Singh +8
Structural, vibrational and dielectric properties of (Pb1-xBix)(Ti1-xMnx)O3 (PBTM) (0 x 0.50) polycrystalline ceramics have been examined as a function of temperature. Synchrotron-…
Investigation of La and Al substitution on the spontaneous polarization and lattice dynamics of the Pb(1-x)LaxTi(1-x)AlxO3 ceramics
Arun Kumar Yadav, Anita Verma, Sunil Kumar +6
The phase purity and crystal structure of PLTA samples (synthesized via sol-gel process) were confirmed using synchrotron x-ray powder diffraction (wavelength, lmbda= 0.44573 A. Ri…
Structural and ferroelectric properties of perovskite Pb(1-x)(K0.5Sm0.5)xTiO3 ceramics
Arun Kumar Yadav, Anita Verma, Sunil Kumar +5
PbTiO3 has the highest tetragonal distortion (c/a=1.064) and highest spontaneous polarization among perovskite titanates. But, it is hazardous and hence one needs to reduce Pb cont…
Structural and dielectric properties of Pb(1-x)(Na0.5Sm0.5)xTiO3 ceramics
