Evidence of structural phase transition in superconducting SmFeAsO_(1-x)F_x from 19^F NMR
M. Majumder, K. Ghoshray, C. Mazumdar +4
We report the resistivity, magnetization and 19^F NMR results in polycrystalline sample of SmFeAsO_(0.86)F_(0.14). The resistivity and the magnetization data show a sharp drop at 4…
Scaling of NonOhmic Conduction in Strongly Correlated Systems
D. Talukdar, U. N. Nandi, A. Poddar +2
A new scaling formalism is used to analyze nonlinear I-V data in the vicinity of metal-insulator transitions (MIT) in five manganite systems. An exponent, called the nonlinearity e…
Interplay between Co-3d and Ce-4f magnetism in CeCoAsO
Rajib Sarkar, Anton Jesche, Cornelius Krellner +4
We have investigated the ground state properties of polycrystalline CeCoAsO by means of magnetization, specific heat and solid state NMR. Susceptibility and specific-heat measureme…
Reproducibility of room temperature ferromagnetism in Zn0.95Mn0.05O and its understanding
R. N. Bhowmik, Asok Poddar, A. Saravanan
The present work reproduces the room temperature ferromagnetism by doping magnetic Mn atoms in diamagnetic ZnO. The ferromagnetic ordering is extended up to 640 K in mechanical mil…
Disorder Effects in La substituted ferrimagnetic Ca2FeMoO6 double perovskite
I. Panneer Muthuselvam, Asok Poddar, R. N. Bhowmik
Ca2-xLaxFeMoO6 double perovskite with La concentration x = 0 to 0.6 was synthesized using solid state sintering route. The standard techniques of XRD, SEM and EDX were applied to c…
Magnetic Response of NiFe2O4 nanoparticles in polymer matrix
A. Poddar, R. N. Bhowmik, Amitabha De +1
We report the magnetic properties of magnetic nano-composite, consisting of different quantity of NiFe2O4 nanoparticles in polymer matrix. The nanoparticles exhibited a typical mag…
