Magnetization Reversal Across Multiple Serial Barriers in a Single FeO Nanoparticle
Sagar Paul, Ganesh Kotagiri, Rini Ganguly +4
Depinning of nanoscale magnetic textures, such as domain walls, vortices and skyrmions, is of paramount importance for magnetic storage and information processing. We measure time-…
Stochastic resonance in thermally bistable Josephson weak-links and micro-SQUIDs
Sagar Paul, Ganesh Kotagiri, Rini Ganguly +3
Constriction-based Josephson weak-links display a thermal bi-stability between two states exhibiting zero and finite voltages. This manifests in experiments either as hysteresis in…
Non-invasive nanoscale potentiometry and ballistic transport in epigraphene nanoribbons
A. De Cecco, V. S. Prudkovskiy, D. Wander +4
The recent observation of non-classical electron transport regimes in two-dimensional materials has called for new high-resolution non-invasive techniques to locally probe electron…
Robust pseudogap across the magnetic field driven superconductor to insulator-like transition in strongly disordered NbN films
Indranil Roy, Rini Ganguly, Harkirat Singh +1
We investigate the magnetic field evolution of the superconducting state in a strongly disordered NbN thin film which exhibits a magnetic field tuned superconductor to insulator-li…
Magnetic field induced emergent inhomogeneity in a superconducting film with weak and homogeneous disorder
Rini Ganguly, Indranil Roy, Anurag Banerjee +3
When a magnetic field is applied, the mixed state of a conventional Type II superconductor gets destroyed at the upper critical field Hc2, where the normal vortex cores overlap wit…
Orientational coupling between the vortex lattice and the crystalline lattice in a weakly pinned Co0.0075NbSe2 single crystal
Somesh Chandra Ganguli, Harkirat Singh, Rini Ganguly +3
We report experimental evidence of strong orientational coupling between the crystal lattice and the vortex lattice in a weakly pinned Co-doped NbSe2 single crystal through direct…
Slowing down of vortex motion in thin NbN films near the superconductor-insulator transition
Rini Ganguly, Dipanjan Chaudhuri, Pratap Raychaudhuri +1
We present a quantitative comparison between the measurements of the complex conductance at low (kHz) and high (GHz) frequency in a thin superconducting film of NbN and the theoret…
Two step disordering of the vortex lattice across the peak effect in a weakly pinned Type II superconductor, Co0.0075NbSe2
Somesh Chandra Ganguli, Harkirat Singh, Garima Saraswat +5
The vortex lattice in a Type II superconductor provides a versatile model system to investigate the order-disorder transition in a periodic medium in the presence of random pinning…
Real space imaging of metastable Bragg glass states in a weakly pinned Type II superconductor
Garima Saraswat, Somesh Chandra Ganguli, Rini Ganguly +5
The breakdown of crystalline order in a disordered background connects to some of the most challenging problems in condensed matter physics. For a superconducting vortex lattice, t…
