Recently, detailed real-space imaging using scanning tunneling spectroscopy of the vortex
lattice in a weakly pinned a-MoGe thin film revealed that the vortex lattice melts in two steps …

Superconductivity occurs in metals when attractive interactions between electrons promote
the formation of Cooper pairs which get locked in a phase-coherent state, leading to …

The hexatic phase is an intermediate stage in the melting process of a 2D crystal due to
topological defects. Recently, this exotic phase was experimentally identified in the vortex …

We find transport and spectroscopic signatures that are consistent with a magnetic field
induced transition from a vortex liquid to Bose metal in a two-dimensional amorphous …

We extract the vortex lattice (VL) parameters using low-frequency two-coil mutual inductance
measurements in a 20-nm-thick superconducting amorphous Molybdenum-Germanium (a …

In a type-II superconductor, the vortex core (VC) behaves like a normal metal. Consequently,
the single-particle density of states in the VC of a conventional type-II superconductor …

We investigate the low-frequency electrodynamics in the vortex state of two type-II
superconducting films, namely, a moderate-to-strongly pinned Niobium Nitride (NbN) and a …

In a two-dimensional superconducting vortex lattice, the melting from the solid to the
isotropic liquid can occur via an intermediate phase that retains orientational correlations …

The nonreciprocal, diode-like electric transport in a superconductor/ferromagnet bilayer
system, MoGe/Ni 81 Fe 19, has been investigated. We found that a MoGe film on Ni 81 Fe …

We report the growth, characterization and superconducting properties of thin films of a new
amorphous superconductor, Re x Zr (x≈ 6). Films were grown by pulsed laser deposition …
