Band Structure of Topological Insulator BiSbTe1.25Se1.75
H. Lohani, P. Mishra, A. Banerjee +6
We present our angle resolved photoelectron spectroscopy (ARPES) and density functional theory results on quaternary topological insulator (TI) BiSbTe1.25Se1.75 (BSTS) confirming t…
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…
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…
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…
