Robust coupling of superconducting order parameter in a mesoscale NbN-Fe-NbN epitaxial structure
S. K. Bose, R. C. Budhani
We report an unconventional and promising route to self-assemble distributed superconductor-ferromagnet-superconductor (S-F-S) Josephson Junctions on single crystal [100] MgO. Thes…
Lattice-mismatch-induced granularity in CoPt-NbN and NbN-CoPt superconductor-ferromagnet heterostructures: Effect of strain
R. K. Rakshit, S. K. Bose, R. Sharma +2
The effect of strain due to lattice mismatch and of ferromagnetic (FM) exchange field on superconductivity (SC) in NbN-CoPt bilayers is investigated. Two different bilayer systems…
Inhomogeneous vortex-state-driven enhancement of superconductivity in nanoengineered ferromagnet-superconductor heterostructures
R. K. Rakshit, R. C. Budhani, T. Bhuvana +2
Thin film heterostructures provide a powerful means to study the antagonism between superconductivity (SC) and ferromagnetism (FM). One interesting issue in FM-SC hybrids which def…
Correlation between incoherent phase fluctuations and disorder in YPrBaCuO epitaxial films from Nernst effect measurements
Pengcheng Li, Soumen Mandal, R. C. Budhani +1
Measurements of Nernst effect, resistivity and Hall angle on epitaxial films of YPrBaCuO(Pr-YBCO, 00.4) are reported over a broad range of t…
Reentrant stability of superconducting films
V. V. Yurchenko, D. V. Shantsev, M. R. Nevala +4
We propose a mechanism responsible for the abrupt vanishing of the dendritic flux instability found in many superconducting films when an increasing magnetic field is applied. The…
Appearance of an inhomogeneous superconducting state in La{0.67}Sr{0.33}MnO{3}-YBa{2}Cu{3}O{7}-La{0.67}Sr{0.33}MnO{3} trilayers
K. senapati, R. C. Budhani
An experimental study of proximity effect in La{0.67}Sr{0.33}MnO3 - YBa2Cu3O7 - La{0.67}Sr{0.33}MnO3 trilayers is reported. Transport measurements on these samples show clear oscil…
