EBand ESe, respectively.\({E}_{{ABSe}_{3}}\)is the energy of the ABSe3unit cell. Materials having low (negative) formation energies are more stable and less prone to break down into their constituent elements. This stability is essential for sustaining the efficiency of perovskite...
One example is the BiFeO3 compound, which represents a rare case with magnetic and ferroelectric ordering coexisting at room temperature (Lebeugle et al., 2008). Another important material that marked the beginning of the success of this family of compounds is YMnO3, characterized by a ...
Novel rare earth metal compounds with the formula [Ln6(O)(OH)8(H2O)12(NO3)6](NO3)2·xH2O, Ln Y, Gd, Yb, x(Y, Yb) = 4; x(Gd) = 5 (Y-BN, GdBN and YbBN) containing clusters of the type M6X8 were prepared and their structures determined. ... Z ?Ák,P Unfried,G Gi...
Antiferromagnetic Ba substituted SrMnO3 has a perovskite structure with a B-site magnetic ion which gives higher magnetic ordering temperatures. Ferroelectric transitions in these perovskites have been observed due to off centering of Mn4+ ions. In this work, we report synthesis of Sr1-xBaxMnO3 (...
Dried gel is found to be magnetically attractive which is observed to get decreased with increasing calcination temperature. The bulk structural, magnetic and ferroelectric properties have been studied in the dried gel subjected to different annealing treatments leading to the formation of the ...
Luminescence and excitation of luminescence vibronic spectra as well as IR and Raman spectra of europium nitrates with 1,10-phenanthroline derivatives of formula Eu(NO3)(3).Ph-2 were studied. The effect of size of ligands and their effective charges on crystal structure and, as a consequence,...
Metal-Insulator Phase Transition and Structural Stability in 'Sb' Doped CaMnO3 Perovskite Electron doped Ca1-xSbx MnO3 (X = 0 to 0.4) compound when prepared by high temperature solid state reaction, exhibits orthorhombic distorted perovskite structure. A systematic, continuous doping increases the ...
