Phonon-pair-driven Ferroelectricity Causes Costless Domain-walls and Bulk-boundary Duality
Hyun-Jae Lee, Kyoung-June Go, Pawan Kumar +10
Ferroelectric domain walls, recognized as distinct from the bulk in terms of symmetry, structure, and electronic properties, host exotic phenomena including conductive walls, ferro…
Multiferroic and magnetoelectric nature of GaFeO3, AlFeO3 and related oxides
Rana Saha, Ajmala Shireen, Sharmila N. Shirodkar +3
GaFeO3, AlFeO3 and related oxides are ferrimagnetic exhibiting magnetodielectric effect. There has been no evidence to date for ferroelectricity and hence multiferroicity in these…
Temperature-dependent Raman study of CeFeAsO0.9F0.1 Superconductor: Crystal field excitations, phonons and their coupling
Pradeep Kumar, Anil Kumar, Surajit Saha +5
We report temperature-dependent Raman spectra of CeFeAsO0.9F0.1 from 4 K to 300 K in spectral range of 60 to 1800 cm-1 and interpret them using estimates of phonon frequencies obta…
