Temperature dependent magnetic, dielectric and Raman studies of partially disordered La2NiMnO6
Pradeep Kumar, S. Ghara, B. Rajeswaran +3
We report a detailed magnetic, dielectric and Raman studies on partially disordered and biphasic double perovskite La2NiMnO6. DC and AC magnetic susceptibility measurements show tw…
Interplay of 4f-3d Magnetism and Ferroelectricity in DyFeO3
B. Rajeswaran, D. Sanyal, Mahuya Chakrabarti +3
DyFeO3 exhibits a weak ferromagnetism (TNFe ~ 645 K) that disappears below a spin-reorientation (Morin) transition at TSRFe ~ 50 K. It is also known that applied magnetic field ind…
Field-induced Polar Order at the Néel Temperature of Chromium in Rare-earth Orthochromites: Interplay of Rare-earth and Cr Magnetism
B. Rajeswaran, D. I. Khomskii, A. K. Zvezdin +2
We report field-induced switchable polarization (P = 0.2 ~ 0.8 microC/cm2) below the Néel temperature of chromium (TN Cr) in weakly ferromagnetic rareearth orthochromites, RCrO3 (R…
Spin-phonon coupling in multiferroic RCrO (R-Y, Lu, Gd, Eu, Sm): A Raman study
Venkata Srinu Bhadram, B. Rajeswaran, A. Sundaresan +1
Raman study on a select few orthochromites, RCrO (R = Y, Lu, Gd, Eu and Sm) shows that the phonon behavior at TN in compounds with magnetic R-ion (Gd and Sm) is remarkably diff…
Ferroelectricity at the Néel Temperature of Chromium in Rare-earth Orthochromites: Interplay of Rare-earth and Cr Magnetism
B. Rajeswaran, D. I. Khomskii, A. K. Zvezdin +2
We report ferroelectricity with fairly large spontaneous polarization (P ~ 0.2 - 0.8 \muC/cm2) below the Néel temperature of chromium (TNCr) in weakly ferromagnetic rare-earth orth…
