Ceramic processing and multiferroic properties of the perovskite YMnO-BiFeO binary system
Jose A. Quintana-Cilleruelo, Alicia Castro, Harvey Amorin +4
The perovskite (1-x)YMnO-xBiFeO binary system is very promising because of its multiferroic end members. Nanocrystalline phases have been recently obtained by mechanosynthe…
Origin of relaxor behavior in barium-titanate based lead-free perovskites
Vignaswaran Veerapandiyan, Maxim N. Popov, Florian Mayer +12
It is well known that disordered relaxor ferroelectrics exhibit local polar correlations. The origin of localized fields that disrupt long range polar order for different substitut…
Hexavalent (Me-W/Mo)-modified (Ba,Ca)TiO-Bi(Mg,Me)O perovskites for high-temperature dielectrics
Thomas Schulz, Vignaswaran K. Veerapandiyan, Theresa Gindel +2
We report on the synthesis of complex lead-free perovskite-type (1-x)(BaCa)TiO-xBi(MgW)O (BCT-xBMW) and (1-x)(BaCa)TiO…
Strategies to Improve the Energy Storage Properties of Perovskite Lead-Free Relaxor Ferroelectrics: A Review
Vignaswaran Veerapandiyan, Federica Benes, Theresa Gindel +1
Electrical energy storage systems (EESSs) with high energy density and power density are essential for the effective miniaturization of future electronic devices. Among different E…
Raman spectra of fine-grained materials from first principles
Maxim N. Popov, Jürgen Spitaler, Vignaswaran K. Veerapandiyan +3
Raman spectroscopy is an advantageous method for studying the local structure of materials, but the interpretation of measured spectra is complicated by the presence of oblique pho…
Dielectric and structural studies of ferroelectric phase evolution in dipole pair substituted barium titanate ceramics
Vignaswaran K. Veerapandiyan, Marco Deluca, Scott T. Misture +3
Ba{[Gax,Tax]Ti(1-2x)}O3 ceramics with x equal to 0, 0.0025, 0.005, 0.01, 0.025 and 0.05 have been prepared by conventional solid-state reaction. Structural and dielectric character…
Atomic scale symmetry and polar nanoclusters in the paraelectric phase of ferroelectric materials
Andreja Bencan, Emad Oveisi, Sina Hashemizadeh +6
The nature of the "forbidden" local- and long-range polar order in nominally nonpolar paraelectric phases of ferroelectric materials has been an open question since the discovery o…
