Multi-vortex versus interstitial vortices scenario in superconducting antidot arrays
A. D. Thakur, S. Ooi, S. P. Chockalingam +3
In superconducting thin films, engineered lattice of antidots (holes) act as an array of columnar pinning sites for the vortices and thus lead to vortex matching phenomena at comme…
Penetration depth and tunneling studies in very thin epitaxial NbN films
Anand Kamlapure, Mintu Mondal, Madhavi Chand +6
We investigate evolution of the magnetic penetration depth and superconducting energy gap in epitaxial NbN films using a low frequency mutual inductance technique and tunneling spe…
Observation of Vortex Matching Phenomena in Antidot Array of NbN Thin Film
Ajay D. Thakur, Shuuichi Ooi, Subbaiah P. Chockalingam +3
We report vortex matching phenomenon in rectangular antidot array fabricated on epitaxial NbN thin film. The antidot array was fabricated using Focussed Ion Beam milling technique.…
Temperature dependence of resistivity and Hall-coefficient in a strongly disordered metal: NbN
Madhavi Chand, Archana Mishra, Y. M. Xiong +8
We report the temperature dependence of resistivity (rho) and Hall coefficient (R_H) in the normal state of homogeneously disordered epitaxial NbN thin films with kFl~3.27-10.12. T…
Vortex matching effect in engineered thin films of NbN
Ajay D. Thakur, Shuuichi Ooi, Subbaiah P. Chockalingam +3
We report robust vortex matching effects in antidot arrays fabricated on thin films of NbN. The near absence of hysteresis between field sweep directions indicates a negligible res…
