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…
Efficient flexible boundary conditions for long dislocations
Max Hodapp
We present a novel efficient implementation of the flexible boundary condition (FBC) method, initially proposed by Sinclair et al., for large single-periodic problems. Efficiency i…
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…
