Non-linear vortex dynamics in the mixed state of superconducting a-MoGe and NbN thin films using low-frequency two-coil mutual inductance technique
Somak Basistha, Soumyajit Mandal, John Jesudasan +2
We use a two-coil mutual inductance technique to investigate the non-linear response of the vortex lattice of two type-II superconducting thin films, namely a very weakly pinned am…
Low frequency electrodynamics in the mixed state of superconducting NbN and a-MoGe films using two-coil mutual inductance technique
Somak Basistha, Soumyajit Mandal, John Jesudasan +2
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 very we…
Study of vortex dynamics in an a-MoGe thin film using low-frequency two-coil mutual inductance measurements
Soumyajit Mandal, Somak Basistha, John Jesudasan +2
We extract the vortex lattice parameters using low-frequency two-coil mutual inductance measurements in a 20-nm-thick superconducting a-MoGe thin film. We fit the temperature depen…
Fast magnetic field amplification in distant galaxyclusters
Gabriella Di Gennaro, Reinout J. van Weeren, Gianfranco Brunetti +16
In the present-day Universe, magnetic fields pervade galaxy clusters, with strengths of a few microGauss obtained from Faraday Rotation. Evidence for cluster magnetic fields is als…
Destruction of superconductivity through phase fluctuations in ultrathin a-MoGe films
Soumyajit Mandal, Surajit Dutta, Somak Basistha +6
We investigate the evolution of superconductivity with decreasing film thickness in ultrathin amorphous MoGe (a-MoGe) films using a combination of sub-Kelvin scanning tunneling spe…
Extreme sensitivity of the vortex state in a-MoGe films to radio-frequency electromagnetic perturbation
Surajit Dutta, Indranil Roy, Soumyajit Mandal +3
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…
Evidence of quantum vortex fluid in the mixed state of a very weakly pinned a-MoGe thin film
Surajit Dutta, Indranil Roy, Soumyajit Mandal +4
Quantum fluids refer to a class of systems that remain in fluid state down to absolute zero temperature. In this letter, using a combination of magnetotransport and scanning tunnel…
Melting of the vortex lattice through intermediate hexatic fluid in a-MoGe thin film
Indranil Roy, Surajit Dutta, Aditya N. Roy Choudhury +8
The hexatic fluid refers to a phase in between a solid and a liquid which has short range positional order but quasi-long range orientational order. In the celebrated theory of Ber…
