Microstructural studies on lattice imperfections in irradiated Titanium and Ti-5%Ta-2%Nb by X-Ray Diffraction Line Profile Analysis
P. Mukherjee, A. Sarkar, P. Barat +2
The microstructural parameters like the average domain size, effective domain size at a particular crystallographic direction and microstrain within the domains of titanium and Ti-…
Double metal-insulator transitions and magnetoresistance:An intrinsic feature of Ru substituted La(0.67)Ca(0.33)MnO(3)
L. Seetha Lakshmi, V. Sridharan, R. Rawat +4
In this paper, we examine the possible influence of extrinsic factors on the electrical and magnetotransport of La(0.67)Ca(0.33)Mn(1-x)Ru(x)O(3) (x < 0.10). These results not only…
Enhanced thermopower upon Ni substitution in Na0.75CoO2
N. Gayathri, A. Bharathi, Y. Hariharan
Thermopower measurements have been carried out on the Ni substituted samples of Na0.75CoO2 in the temperature range 4.2K to 300K. The room temperature TEP increases by 20microV/K e…
Effect of Mn substitution on the delicate balance between structure and properties of Gd1.4Ce0.6Sr2RuCu2O10
S. Kalavathi, J. Janaki, T. N. Sairam +3
Some new members of a Ruthenocuprate (2212) series have been synthesized by Mn substitution for Ru in Gd1.4Ce0.6Sr2RuCu2O10 . Characterisation by XRD phase analysis followed by Rie…
Detecting onset of chain scission and crosslinking of gamma-ray irradiated elastomer surfaces using frictional force microscopy
S. Banerjee, N. K. Sinha, N. Gayathri +4
We report here that atomic force microscope (AFM) in frictional force mode can be used to detect onset of chain scission and crosslinking in polymeric and macromolecular samples up…
Drastic ground state changes induced by Ni substitution in NaxCoO2
N. Gayathri, M. Premila, A. Bharathi +3
We report on the effect of Ni substitution at the Co site on the physical properties of NaxCoO2 system by investigating the series NaxCo1-yNiyO2 (x=0.75, 0<y<0.15). An upturn in th…
