Spin-Reorientation, Ferroelectricity, and Magnetodielectric Effect in YFe(1-x)Mn(x)O(3)(0.1 <= x <= 0.40)

Mandal, P; Bhadram, Venkata Srinu; Sundarayya, Y; Narayana, Chandrabhas; Sundaresan, A; Rao, C N R (American Physical Society, 2011-09-19)

We report the observation of magnetoelectric and magnetodielectric effects at different temperatures in Mn-substituted yttrium orthoferrite, YFe(1-x)Mn(x)O(3)(0.1 <= x <= 0.40). Substitution of Mn in antiferromagnetic ...
Brillouin Scattering Investigation of Solvation Dynamics in Succinonitrile-Lithium Salt Plastic Crystalline Electrolytes

Das, Supti; Bhadram, Venkata Srinu; Narayana, Chandrabhas; Bhattacharyya, Aninda J (American Chemical Society, 2011-11-03)

Temperature dependent Brillouin scattering studies have been performed to ascertain the influence of solvent dynamics on ion-transport in succinonitrile-lithium salt plastic crystalline electrolytes. Though very rarely ...
A low-cost Raman spectrometer design used to study Raman scattering from a single-walled carbon nanotube

Kavitha, G; Vivek, S R C; Govindaraj, A; Narayana, Chandrabhas (Indian Academy of Sciences, 2003-10)

The paper discusses the design of a low cost Raman spectrometer. Singlewalled nanotubes (SWNT) have been studied to demonstrate the reach of such a system. We observe both the radial-breathing mode (RBM) and the tangential ...
Sevenfold Coordinated MgSe: Experimental Internal Atom Position Determination to 146 GPa, Diffraction Studies to 202 GPa, and Theoretical Studies to 500 GPa

Ruoff, A L; Ho, A C; Pai, M F; Luo, H; Greene, R G; Chandrabhas, Narayana; Molstad, J C; Trail, S S; DiSalvo, F J; van Camp, P E (American Physical Society, 1998-09-28)

MgSe has been studied using energy dispersive x-ray diffraction to 202 GPa and local density approximation and ultrasoft pseudopotentials to 500 GPa. MgSe undergoes a "continuous" phase transformation from the rocksalt to ...
