Electric toroidal dipole order and hidden spin polarization in ferroaxial materials
Sayantika Bhowal, Nicola A. Spaldin
We investigate the role of electric toroidal dipoles in the prototypical ferroaxial materials NiTiO and KZr(PO), which undergo ferroaxial structural phase transitio…
Orbital Hall effect in bilayer transition metal dichalcogenides: From the intra-atomic approximation to the Bloch states orbital magnetic moment approach
Tarik P. Cysne, Sayantika Bhowal, Giovanni Vignale +1
Using an effective Dirac model, we study the orbital Hall effect (OHE) in bilayers of transition metal dichalcogenides with 2H stacking (2H-TMD). We use first-order perturbation th…
Spin wave excitations in the pyrovanadate alpha-Cu2V2O7
A. Banerjee, J. Sannigrahi, S. Bhowal +5
The pyrovanadate alpha-Cu2V2O7 belongs to the orthorhombic (Fdd2) class of crystals with noncentrosymmetric crystal structure. Recently, the compound has been identified to be a ma…
Exchange striction induced giant ferroelectric polarization in copper based multiferroic material -CuVO
J. Sannigrahi, S. Bhowal, S. Giri +2
We report -CuVO to be an improper multiferroic with the simultaneous development of electric polarization and magnetization below = 35 K. The observed spontane…
Magnetic properties and heat capacity of the three-dimensional frustrated S=1/2 antiferromagnet PbCuTe2O6
B. Koteswararao, R. Kumar, P. Khuntia +8
We report magnetic susceptibility (chi) and heat capacity Cp measurements along with ab-initio electronic structure calculations on PbCuTe2O6, a compound made up of a three dimensi…
Effect of spin orbit coupling and Hubbard on the electronic structure of IrO
S. K. Panda, S. Bhowal, A. Delin +2
We have studied in detail the electronic structure of IrO including spin-orbit coupling (SOC) and electron-electron interaction, both within the GGA+U and GGA+DMFT approximatio…
