Journal ArticleDOI
Enhanced bulk photovoltaic response in Sn doped BaTiO3 through composition dependent structural transformation
TL;DR: The experimental and theoretical studies indicate that the sample with the orthorhombic phase is preferable for the enhanced photovoltaic response in comparison to the tetragonal phase.
Journal ArticleDOI
Effect of frustrated exchange interactions and spin-half-impurity on the electronic structure of strongly correlated NiFe 2 O 4
Kodam Ugendar,Subhasis Samanta,Sudhindra Rayaprol,Vasudeva Siruguri,G. Markandeyulu,Birabar Nanda +5 more
TL;DR: In this article, a spin-frustrated triangular lattice with one of the vertices occupied by tetrahedral spins and the remaining two occupied by octahedral spins was investigated.
Journal ArticleDOI
Second-neighbor electron hopping and pressure induced topological quantum phase transition in insulating cubic perovskites
TL;DR: In this article, the authors predict a Dirac semimetal topological insulator phase transition with uniform compression using density functional calculations on cubic perovskites with the aid of a Slater-Koster tight binding Hamiltonian, apart from the valence electron count, the band topology of these perovksites is determined by five parameters involving electron hopping among the Sn-$s,p$} orbitals.
Journal ArticleDOI
Spin-glass state in nanoparticulate (La0.7Sr0.3MnO3)(1-x) (BaTiO3)(x) solid solutions: Experimental and density-functional studies
Chiranjib Nayek,Subhasis Samanta,Kaustuv Manna,Anuj Pokle,Birabar Nanda,P. S. Anil Kumar,Pattukkannu Murugavel +6 more
TL;DR: In this paper, the transition from robust ferromagnetism to spin-glass state in nanoparticulate La0.7Sr0.3MnO3 through solid solution with BaTiO3 was reported.
Journal ArticleDOI
Topologically invariant double Dirac states in bismuth-based perovskites: Consequence of ambivalent charge states and covalent bonding
TL;DR: In this paper, the authors reveal the existence of two TI states, one in valence band (V-TI) and the other in conduction band (C-TI), as the universal feature of perovskite families.
