Engineering room-temperature multiferroicity in Bi and Fe codoped BaTiO3
Pratap Pal, Tapas Paramanik, Krishna Rudrapal +8
Fe doping into BaTiO3, stabilizes the paraelectric hexagonal phase in place of the ferroelectric tetragonal one [P. Pal et al. Phys. Rev. B, 101, 064409 (2020)]. We show that simul…
Site-substitution in GdMnO3 : effects on structural, electronic and magnetic properties
Sudipta Mahana, Bipul Rakshit, Pronoy Nandi +5
We report on detailed structural, electronic and magnetic studies of GdMnCrO for Cr doping levels 0 1. In the solid solutions, the Jahn-Teller disto…
Origin and tuning of room-temperature multiferroicity in Fe doped BaTiO
Pratap Pal, Krishna Rudrapal, Sudipta Mahana +5
Simultaneous co-existence of room-temperature(T) ferromagnetism and ferroelectricity in Fe doped BaTiO (BTO) is intriguing, as such Fe doping into tetragonal BTO, a room-T ferr…
Tetramer Orbital-Ordering induced Lattice-Chirality in Ferrimagnetic, Polar MnTi2O4
A. Rahaman, M. Chakraborty, T. Paramanik +6
Using density-functional theory calculations and experimental investigations on structural, magnetic and dielectric properties, we have elucidated a unique tetragonal ground state…
Role of local structural distortion in driving ferroelectricity in GdCrO3
Sudipta Mahana, U. Manju, Pronoy Nandi +3
Temperature dependent synchrotron x-ray diffraction and extended x-ray absorption fine structure (EXAFS) studies were performed to understand the role of structural characteristics…
Defect induced polarization and dielectic relaxation in GaFeO
Sudipta Mahana, C. Dhanasekhar, A. Venimadhav +1
We report results of the dielectric and pyroelectric measurements on solid solutions of GaFeO with x = 0.75, 1.0 and 1.25. These systems exhibit dipolar cluster…
Local inversion symmetry breaking and spin-phonon coupling in perovskite GdCrO3
Sudipta Mahana, Bipul Rakshit, Raktima Basu +5
Our detailed temperature dependent synchrotron powder x-ray diffraction studies along with first-principles density functional perturbation theory calculations, enable us to shed l…
Structural and electronic phase evolution of Tin dioxide
Sudipta Mahana, Pitamber Sapkota, Saptarshi Ghosh +2
We investigate the effect of controlled annealing on the structural and electronic phase evolution of Tin dioxide from Tin (II) oxyhydroxide prepared by simple precipitation method…
Giant magnetocaloric effect in Gd2NiMnO6 and Gd2CoMnO6 ferromagnetic insulators
J. Krishna Murthy, K. Devi Chandrasekhar, Sudipta Mahana +2
We have investigated magnetocaloric effect in double perovskite Gd2NiMnO6 (GNMO) and Gd2CoMnO6 (GCMO) samples by magnetic and heat capacity measurements. Ferromagnetic ordering is…
