Vortex dynamics and second magnetization peak in PrFeAsOF superconductor
D. Bhoi, P. Mandal, P. Choudhury
We have studied the vortex dynamics in the PrFeAsOF superconducting sample by dc magnetization and dynamic magnetization-relaxation rate measurements. The f…
Fe-spin reorientation in PrFeAsO : Evidences from resistivity and specific heat studies
D. Bhoi, P. Mandal, P. Choudhury +2
We report the magnetic field dependence of resistivity () and specific heat () for the non-superconducting PrFeAsO compound. Our study shows a hitherto unobserved anomaly at…
Multiferroic coupling in nanoscale BiFeO3
S. Goswami, Dipten Bhattacharya, P. Choudhury +2
Using the results of x-ray and neutron diffraction experiments, we show that the ferroelectric polarization, in ~22 nm particles of BiFeO3, exhibits a jump by ~30% around the magne…
Quantm Magnetoresistance of the PrFeAsO oxypnictides
D. Bhoi, P. Mandal, P. Choudhury +2
We report the observation of an unusual dependence of transverse magnetoresistance (MR) in the PrFeAsO, one of the parent compound of pnictide superconductors. Below the spin d…
Particle size dependence of magnetization and non-centrosymmetry in nanoscale BiFeO3
Sudipta Goswami, Dipten Bhattacharya, P. Choudhury
The saturation magnetization (M_s), antiferromagnetic transition point (T_N), and the off-center displacements of Bi and Fe ions have been measured as a function of particle size i…
The magnetization of PrFeAsOF$_{0.12} sueprconductor
D. Bhoi, P. Mandal, P. Choudhury +2
The magnetization of the PrFeAsOF polycrystalline sample has been measured as functions of temperature and magnetic field . The observed total magnetization…
