Wasp -- Waisted loop and Spin frustration in DyEuTiO Pyrochlore
Prajyoti Singh, Arkadeb Pal, Vinod K. Gangwar +6
The Raman spectroscopy and AC and DC magnetization of DyEuTiO have been investigated. In Raman Spectroscopy, the systematic shift in all phonon modes with Eu co…
Pressure induced Superconductivity and location of Fermi energy at Dirac point in BiSbTe3
Vinod K. Gangwar, Shiv Kumar, Mahima Singh +8
We have grown single-crystal BiSbTe3 3D TI sample and studied structural, TE as well as pressure dependent magneto-transport properties. Large positive Seebeck coefficient confirme…
Probing the Griffiths like phase, unconventional dual glassy states, giant exchange bias effects and its correlation with its electronic structure in Pr2-xSrxCoMnO6
Arkadeb Pal, Prajyoti Singh, Vinod K Gangwar +7
Electronic structure, electrical transport, dc and ac magnetization properties of the hole substituted (Sr2+) partially B-site disordered double perovskite Pr2-xSrxCoMnO6 system ha…
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…
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)…
