Monoclinic symmetry at the nanoscale in lead-free ferroelectric BaZrTiO ceramics
Koushik Dey, Abinash Tripathy, Shikha Rani Sahu +4
Local structural symmetries play a key role in the functionalities of ferroelectric materials and are often found different from average symmetry. Here, we study the real space nan…
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…
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,…
Natural ferroelectric order near ambient temperature in HoFeO3: A member of RFeO3 orthoferrites
K. Dey, A. Indra, S. Mukherjee +6
Current scenario in multiferroics demands a breakthrough discovery of promising materials after BiFeO3. Recently, the controversial discovery of room temperature ferroelectricity (…
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…
Role of the V-V dimerization in insulator-metal transition and optical transmittance of pure and doped VO2 thin films
S. S. Majid, S. R. Sahu, A. Ahad +7
Insulator to metal (IMT) transition (T 341 K) in the VO2 accompanies transition from an infrared (IR) transparent to IR opaque phase. Tailoring of the IMT and associated…
