Coupled Phonons, Magnetic Excitations and Ferroelectricity in AlFeO3: Raman and First-principles Studies
Pradeep Kumar, A. Bera, D. V. S. Muthu +7
We determine the nature of coupled phonons and magnetic excitations in AlFeO3 using inelastic light scattering from 5 K to 315 K covering a spectral range from 100-2200 cm-1 and co…

Raman evidence for Orbiton-Mediated Multiphonon Scattering in Multiferroic TbMnO
Pradeep Kumar, Surajit Saha, D. V. S. Muthu +3
Temperature-dependent Raman spectra of TbMnO from 5 K to 300 K in the spectral range of 200 to 1525 cm show five first-order Raman allowed modes and two high frequency m…

An Electron Paramagnetic Resonance Study of Electron-Hole Asymmetry in Charge Ordered Pr_1-x Ca_xMnO_3 (x=0.64, 0.36)
Janhavi P. Joshi, A. K. Sood, S. V. Bhat +2
We present and compare the results of temperature-dependent electron paramagnetic resonance (EPR) studies on Pr_1-x Ca_xMnO_3 for x = 0.64 which is electron-doped with those on the…
