Vibrational Spectra of Pb2Bi2Te3, PbBi2Te4 and PbBi4Te7 Topological Insulators: Temperature Dependent Raman and Theoretical Insight from DFT Simulations
Priyanath Mal, Ganesh Bera, G. R. Turpu +5
We present temperature dependent frequency shift and line broadening of phonon modes by insertion of atomic layers of Pb and PbTe in the prototype 3D topological insulator Bi2Te3,…
Spin-Triplet Vortex State in the Topological Superconductor CuxBi2Se3
Pradip Das, Yusuke Suzuki, Masashi Tachiki +1
We report on the observation of bulk superconductivity from dc magnetization measurements in a cylindrical single crystal of CuxBi2Se3. The magnitude of the magnetization in the Me…
Magnetization hysteresis and time decay measurements in FeSeTe : Evidence for fluctuation in mean free path induced pinning
P. Das, Ajay D. Thakur, Anil K. Yadav +5
We present results of magnetic measurements relating to vortex phase diagram in a single crystal of FeSeTe which displays second magnetization peak anomaly for $H \…
Anisotropy in vortex phase diagram and the pinning force density in the basal plane of YNi_2B_2C
Pradip Das, C. V. Tomy, H. Takeya +2
We present magnetic field dependence of the critical current density from dc-magnetization measurements concerning the anisotropic behavior of flux line lattice (FLL) in a single c…
Peak effect phenomena, surface superconductivity and paramagnetic Meissner effect in a spherical single crystal of niobium
Pradip Das, C. V. Tomy, H. Takeya +2
We have explored the vortex phase diagram in a spherical single crystal of niobium (T ~ 9.3 K) via isothermal and temperature dependent dc magnetization and ac-susceptibility measu…
Thermo-magnetic history effects in the vortex state of YNi_2B_2C superconductor
Pradip Das, C. V. Tomy, H. Takeya +2
The nature of five-quadrant magnetic isotherms for is different from that for in a single crystal of YNi2B2C, pointing towards an anisotropic behaviour of the flux line lattice (FL…
