Coexistence of local structural heterogeneities and long-range ferroelectricity in Pb-free (1-x)Ba(Zr0.2Ti0.8)O3-x(Ba0.7Ca0.3)TiO3 ceramics
Koushik Dey, Abdul Ahad, Kamini Gautam +11
Environmentally benign (1-x)Ba(TiZr)O-x(BaCa)TiO (BZT-BCT) ceramics are promising materials due to their remarkable high piezoresponse [Liu…
Revisiting 70 years of lattice dynamics of BaTiO3: Combined first principle and experimental investigation
Vivek Dwij, Binoy Krishna De, Gaurav Sharma +4
BaTiO3 is a classical ferroelectric studied for last one century for its ferroelectric properties. Lattice dynamics of BaTiO3 is crucial as the utility of devices is governed by ph…
Magnetic correlations in subsystems of the misfit [CaCoO][CoO] cobaltate
Abdul Ahad, K. Gautam, K. Dey +7
[CaCoO][CoO], a two dimensional misfit metallic compound, is famous for its rich phases accessed by temperature, high temperature spin-state transition,…
Magnetic and orbital correlations in multiferroic CaMnO probed by x-ray resonant elastic scattering
K. Gautam, S. S. Majid, S. Francoual +6
The quadruple perovskite CaMnO is a topical multiferroic, in which the hierarchy of electronic correlations driving structural distortions, modulated magnetism, and orbi…
Electric-field-induced pyroelectric order and localization of the confined electrons in LaAlO3/SrTiO3 heterostructures
M. Rössle, K. W. Kim, A. Dubroka +13
With infrared ellipsometry, x-ray diffraction, and electric transport measurements we investigated the electric-field-effect on the confined electrons at the LaAlO3/SrTiO3 interfac…
