Unraveling the temperature-responsive charge-disproportionation in BaBiO
Sumit Sarkar, Priyanka Yadav, Sourav Chowdhury +2
This study shows that the charge disproportionation at the Bi site in BaBiO alters as a function of temperature. Decreasing the temperature from 300K down to 160K leads to a si…
Local symmetry breaking and orbital glass behaviour in CoFe2O4
Soumya Shephalika Behera, Isha, Arvind Kumar Yogi +6
The structural distortions, orbital correlations, and electronic states in cobalt ferrite (CoFe2O4) were investigated using complementary characterisation techniques, including SR-…
Room temperature reversible colossal volto-magnetic effect in all-oxide metallicmagnet/topotactic-phase-transition material heterostructures
Sourav Chowdhury, Supriyo Majumder, Rajan Mishra +6
Multiferroic materials have undergone extensive research in the past two decades in an effort to produce a sizable room-temperature magneto-electric (ME) effect in either exclusive…
Competing s-p and p-p fluctuations in charge-disproportionation of BaBiO3
Sumit Sarkar, Ram Janay Choudhary, Rajamani Raghunathan
Here we investigate the mechanism of charge-disproportionation (CD) in BaBiO3 (BBO) using density functional theory under different crystal symmetries and by employing strain as an…
Temperature and terahertz frequency dependence of the dielectric properties of Fe3O4 thin films deposited on Si substrate
Ashish Khandelwal, L. S. Sharath Chandra, Shilpam Sharma +4
The FeO/Si films are considered to be promising materials for THz spintronic applications due to their high temperature magnetic transition and semiconducting properties. I…
Light-induced giant and persistent changes in the converse magnetoelastic effects in Ni/BaTiO3 multiferroic heterostructure
Anita Bagri, Anupam Jana, Gyanendra Panchal +5
Magnetoelastic and magnetoelectric coupling in the artificial multiferroic heterostructures facilitate valuable features for device applications such as magnetic field sensors and…
