Study of Gravastars in Rastall Gravity
Shounak Ghosh, Sagar Dey, Amit Das +2
Gravastars have been considered as a feasible alternative to black holes in the past couple of decades. Stable models of gravastar have been studied in many of the alternative grav…
Study of gravastars under gravity
Amit Das, Shounak Ghosh, Debabrata Deb +2
In the present paper we propose a stellar model under the gravity following the conjecture of Mazur-Mottola~[Report number: LA-UR-01-5067 (2001); Proc. Natl. Acad.…
Gravastars in gravity
Shounak Ghosh, A. D. Kanfon, Amit Das +3
We propose a stellar model under the gravity following Mazur-Mottola's conjecture [Mazur (2001), Mazur (2004)] known as gravastar which is generally bel…
Structural, magnetic and electric polarization properties of geometrically frustrated YBaCo4O7 and DyBaCo4O7 cobaltites
C. Dhanasekhar, A. K Das, A. Das +3
In RBaCo4O7 (R = Ca, Y and Rare earth) cobaltite family, only CaBaCo4O7 shows 3D long range ferrimagnetic and spin driven electric polarization properties. In the present study, we…
Probing the multi spin-phonon coupling and local B-site disorder in Pr2CoFeO6 by Raman spectroscopy and correlation with its electronic structure by X-ray photoemission spectroscopy
Arkadeb Pal, Surajit Ghosh, Amish G. Joshi +5
Electronic structure near Fermi level of Pr2CoFeO6 (at 300 K) was investigated by X-ray photoemission spectroscopy (XPS) technique. All three cations, i.e., Pr, Co and Fe were foun…
B-site spin-state and anti-site disorder driven multiple-magnetic phases: Griffiths phase, re-entrant cluster glass and exchange bias in double perovskite PrCoFeO
Arkadeb Pal, P. Singh, Shiv Kumar +9
We report the comprehensive experimental results identifying the magnetic spin ordering and the magnetization dynamics of a double perovskite Pr2CoFeO6 by employing the (dc and ac)…
