Improving the critical current density of the $V_{0.59} Ti_{0.40} Ce_{0.01}$ alloy superconductor through successive cold-working and annealing at different temperatures

Asi Khandelwal, SK. Ramjan, Basudev Padhi +5

The critical current density ( $J_{c}$ ) of V-Ti alloy superconductors is strongly influenced by the size and distribution of microstructural defects that pin magnetic flux lines. In t…

Negative temperature coefficient of resistivity due to the itinerant spin fluctuations in metallic V $_{0.3}$ Ti $_{0.7}$ alloy

SK Ramjan, Asi Khandelwal, L. S. Sharath Chandra +1

Few concentrated disordered binary metallic alloys show a negative temperature coefficient of resistivity (TCR), which is quite unusual. V $_{0.3}$ Ti $_{0.7}$ is one such alloy that…

Enhancement of functional properties of V $_{0.6}$ Ti $_{0.4}$ alloy superconductor by the addition of yttrium

SK. Ramjan, L. S. Sharath Chandra, Rashmi Singh +3

We show here that the yttrium is immiscible and precipitates with various sizes in the body centred cubic V $_{0.6}$ Ti $_{0.4}$ alloy superconductor. The number and size of the preci…

Temperature induced first order electronic topological transition in $β$ -Ag $_{2}$ Se

L. S. Sharath Chandra, SK. Ramjan, Soma Banik +2

$β$ -Ag $_{2}$ Se is a promising material for room temperature thermoelectric applications and magneto-resistive sensors. However, no attention was paid earlier to the hysteresis in the…
