Spin freezing and Field induced transition in (Tb1-xEux)2Ti2O7 : A Magnetic Property study
Prajyoti Singh, Arkadeb Pal, Vinod K. Gangwar +4
The structural, magnetic and Raman effect have been investigated on (Tb1-xEux)2Ti2O7. From structural study it is clear that Eu substitutes the Tb in Tb2Ti2O7. Raman effect study i…
Giant longitudinal negative magneto-resistance under perpendicular magnetic field in BiFeSeS Topological insulators
Rahul Singh, Vinod K. Gangwar, Abhishek Singh +5
The magnetic, magneto-transport and ARPES studies of Fe and S co-doped Bi2Se3 were investigated. With doping concentration magneto-resistance (MR) gradually decreases and for a cer…
Room temperature large spontaneous exchange bias in hard-soft antiferromagnetic composite BiFeO3-TbMnO3
Prince Kr. Gupta, Surajit Ghosh, Shiv Kumar +12
We report the presence of giant spontaneous exchange bias (HSEB) in a hard and soft antiferromagnetic composite of BiFeO3-TbMnO3 (BFO-TMO in 7:3 and 8:2 ratio). The HSEB varies bet…
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…
Ground state properties of the bond alternating spin- anisotropic Heisenberg chain
S. Paul, A. K. Ghosh
Ground state properties, dispersion relations and scaling behaviour of spin gap of a bond alternating spin- anisotropic Heisenberg chain have been studied where the ex…
Local structure surrounding V sites in Co doped ZnV2O4
P. Shahi, N. Tiwari, D. Bhattacharyya +6
Co doped ZnV2O4 has been investigated by Synchrotron X-ray diffraction, Magnetization measurement and Extended X-ray absorption fine structure (EXAFS) analysis. With Co doping in t…
