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…
HI power spectrum of the spiral galaxy NGC628
Prasun Dutta, Ayesha Begum, Somnath Bharadwaj +1
We have measured the HI power spectrum of the nearly face-on spiral galaxy NGC628 (M74) using a visibility based estimator. The power spectrum is well fitted by a power law $P(U)=A…
Relativistic calculations of the lifetimes and hyperfine structure constants in Zn
Gopal Dixit, H. S. Nataraj, B. K. Sahoo +2
This work presents accurate {\it ab initio} determination of the magnetic dipole (M1) and electric quadrupole (E2) hyperfine structure constants for the ground and a few low-lying…
Kinematics of deformable media
Anirvan Dasgupta, Hemwati Nandan, Sayan Kar
We investigate the kinematics of deformations in two and three dimensional media by explicitly solving (analytically) the evolution equations (Raychaudhuri equations) for the expan…
Theoretical spectroscopic studies of the atomic transitions and lifetimes of low-lying states in Ti IV
Subhasish Mandal, Gopal Dixit, B. K. Sahoo +2
The astrophysically important electric quadrupole (E2) and magnetic dipole (M1) transitions for the low-lying states of triply ionized titanium (Ti IV) are calculated very accurate…
Ab initio relativistic many-body calculation of hyperfine splitting of ^{113}Cd^+
Gopal Dixit, H. S. Nataraj, B. K. Sahoo +2
This work presents accurate ab initio determination of the hyperfine splitting for the ground state and few low-lying excited states of 113Cd+; important candidates for the frequen…
