Enhanced grain surface effect on magnetic properties of nanometric La0.7Ca0.3MnO3 manganite : Evidence of surface spin freezing of manganite nanoparticles
P. Dey, T. K. Nath, P. K. Manna +1
We have investigated the effect of nanometric grain size on magnetic properties of single phase, nanocrystalline, granular La0.7Ca0.3MnO3 (LCMO) sample. We have considered core-she…
Proposal for an experiment to search for Randall-Sundrum type corrections to Newton's law of gravitation
Mofazzal Azam, M. Sami, C. S. Unnikrishnan +1
String theory, as well as the string inspired brane-world models such as the Randall-Sundrum (RS) one, suggest a modification of Newton's law of gravitation at small distance scale…
Ferromagnetism in cobalt doped n-GaN
S. Dhara, B. Sundaravel, K. G. M. Nair +5
Ferromagnetic ordering is reported in the post-annealed samples of Co doped n-GaN formed by Co+ implantation. A maximum Curie temperature ~ 250K is recorded for the sample with 8 a…
Time-dependent density functional theory calculation of van der Waals coefficient of sodium clusters
Arup Banerjee, Aparna Chakrabarti, Tapan K. Ghanty
In this paper we employ all-electron \textit{ab-initio} time-dependent density functional theory based method to calculate the long range dipole-dipole dispersion coefficient (van…
Centrality dependence of charged hadron production in deuteron+gold and nucleon+gold collisions at sqrt(s_NN)=200 GeV
PHENIX Collaboration, S. S. Adler
We present transverse momentum (p_T) spectra of charged hadrons measured in deuteron-gold and nucleon-gold collisions at \sqrts = 200 GeV for four centrality classes. Nucleon-gold…
The structural and magnetic properties of (In1-xFex)2O3 (0.0 <= x <= 0.25) system : prepared by gel combustion method
O. D. Jayakumar, I. K. Gopalakrishnan, S. K. Kulshreshtha +9
(In1-xFex)2O3 polycrystalline samples with x = (0.0, 0.05, 0.10, 0.15, 0.20 and 0.25) have been synthesized by a gel combustion method. Reitveld refinement analysis of X raydiffrac…
