Anomalies in the electronic structure of a 5 transition metal oxide, IrO
Swapnil Patil, Aniket Maiti, Surajit Dutta +7
Ir-based materials have drawn much attention due to the observation of insulating phase believed to be driven by spin-orbit coupling while Ir 5 states are expected to be weakly…
Evidence of zero point fluctuation of vortices in a very weakly pinned a-MoGe thin film
Surajit Dutta, Indranil Roy, John Jesudasan +2
In a Type II superconductor, the vortex core behaves like a normal metal. Consequently, the single-particle density of states in the vortex core of a conventional Type II supercond…
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…
Experimental test of strong pinning and creep in current-voltage characteristics of type II superconductors
Martin Buchacek, Zhi-Li Xiao, Surajit Dutta +4
Pinning and creep determine the current--voltage characteristic of a type II superconductor and thereby its potential for technological applications. The recent development of stro…
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…
