Pressure induced electronic band evolution and observation of superconductivity in the Dirac semimetal ZrTe5
Sanskar Mishra, Nagendra Singh, Vinod K. Gangwar +8
We report a comprehensive investigation of the pressure effects on the magnetotransport properties of the topological material ZrTe5 within 1 to 8 GPa pressure range. With increasi…
Effect of pressure on the transport properties and thermoelectric performance of Dirac semimetal ZrTe5
Sanskar Mishra, Nagendra Singh, V. K. Gangwar +11
In this study, we have investigated and compared the effect of hydrostatic pressure up to ~20 kbar on the transport properties of ZrTe5 single crystals grown by chemical vapor tran…
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…
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)…
Coexistence of surface and bulk state and negative magnetoresistance in Sulfur doped Bi2Se3
Rahul Singh, Vinod K. Gangwar, D. D. Daga +6
The magneto-transport properties in Sulfur doped Bi2Se3 are investigated. The magnetoresistance (MR) decreases with increase of S content and finally for 7% (i.e. y=0.21) S doping…
