We have investigated the superconducting properties of nanocomposite pellets made from Bi-2223 and Co2C powders. Our measurements reveal loss of superconducting fraction in the nanocomposites. However, the retained superconducting fraction exhibits r

Abstract Two-dimensional (2D) topological surface states in a three-dimensional topological insulator (TI) should produce uniform 2D surface current distribution. However, our transport current imaging studies on Bi2Se3 thin film reveal non-uniform c

The magnetic field dependence of the critical current is studied in single crystal samples of the weak pinning type-II superconductor 2H-NbSe$_2$ in the high temperature and the low field region of the (H,T) phase space, in the vicinity of the reentr

We report on the discovery of the simultaneous observation of Fishtail Effect (FE) and Peak Effect (PE) via the study of angular dependence of dc magnetization hysteresis loops in a clean crystal of 2H-NbSe$_2$. These result clarify and establish the

The reentrant nature of Peak Effect is established in a single crystal of 2H-NbSe_2 via electrical transport and dc magnetisation studies. The role of disorder on the reentrant branch of PE has been examined in three single crystals with varying leve

Abstract Under the influence of a constant drive the moving vortex state in 2H-NbS2 superconductor exhibits a negative differential resistance (NDR) transition from a steady flow to an immobile state. This state possesses a high depinning current thr

Study of the formation and evolution of large scale, ordered structures is an enduring theme in science. Generation, evolution and control of large sized magnetic domains are challenging tasks, given the complex nature of competing interactions in a

We study the validity of the fluctuation relation for a non-equilibrium quantum mechanical system, viz., electrons quantum mechanically tunneling across a periodically modulating barrier. Experimentally this system is realized by measuring the fluctu

We investigate the pinning mechanism in high-critical-current polycrystalline samples of Bi-2223 (Bi2Sr2Ca2Cu3O10) utilized in high current applications. Using differential magneto-optical (DMO) imaging technique, we track the magnetic field penetrat
