The effect of antisite disorder on magnetic and exchange bias properties of Gd-substituted YCoMnO double perovskite
Anasua Khan, Sarita Rajput, M. Anas +4
Combining experimental investigations and first-principles DFT calculations, we report physical and magnetic properties of Gd-substituted YCoMnO double perovskite, which ar…
Electric field and Strain-induced Band-gap Engineering and Manipulation of the Rashba Spin Splitting in Janus van der Waals Heterostructures
Shubham Patel, Urmimala Dey, Narayan Prasad Adhikari +1
The compositional as well as structural asymmetries in Janus transition metal dichalcogenides (J-TMDs) and their van der Waals heterostructures (vdW HSs) induce an intrinsic Rashba…
Electron-Phonon Coupling and Quantum Correction to Topological Magnetoconductivity in Bi2GeTe4
Niraj Kumar Singh, Divya Rawat, Dibyendu Dey +5
We report on structure, vibrational properties and weak-antilocalization-(WAL-) induced quantum correction to magnetoconductivity in single crystal Bi2GeTe4. Surface band structure…
Ferroelectric Polarization in Antiferroelectric Chalcogenide Perovskite BaZrS3 Thin Film
Juhi Pandey, Debjit Ghoshal, Dibyendu Dey +4
Bulk chalcogenide perovskite BaZrS3 (BZS), with a direct band gap in visible region, is an important photovoltaic material, albeit with limited applicability owing to its antiferro…
Phonon dispersion, Raman spectra and evidence for spin-phonon coupling in MnVO from first-principles
Dibyendu Dey, T. Maitra, U. V. Waghmare +1
MnVO in the spinel structure is known to exhibit coupled orbital and spin ordering, and its Raman spectra show interesting anomalies in its low-temperature phase. With a go…
Fascinating interplay between Charge Density Wave Order and magnetic field in Non-magnetic Rare-Earth Tritelluride LaTe
Arnab Pariari, Sudipta Koley, Shubhankar Roy +4
Charge density wave (CDW) states in solids bear an intimate connection to underlying fermiology. Modification of the latter by a suitable perturbation provides an attractive handle…
