Magnetic field tuned superconductor-to-insulator transition at the LaAlO /SrTiO interface
M. M. Mehta, D. A. Dikin, C. W. Bark +4
We present a study of the magnetic field tuned superconductor-to-insulator transition (SIT) in the electron gas that forms at the LaAlO/SrTiO interface. We find that the ma…
Evidence for charge-vortex duality at the LaAlO/SrTiO interface
Manan Mehta, D. A. Dikin, C. W. Bark +4
The concept of duality has proved extremely powerful in extending our understanding in many areas of physics (1, 2). Charge-vortex duality has been proposed (3, 4) as a model to un…
Coexistence of superconductivity and ferromagnetism in two dimensions
D. A. Dikin, M. Mehta, C. W. Bark +3
Ferromagnetism is usually considered to be incompatible with conventional superconductivity, as it destroys the singlet correlations responsible for the pairing interaction. Superc…
Superfluid density measurements of Ba(CoxFe1-x)2As2 films near optimal doping
Jie Yong, S. Lee, J. Jiang +6
We report the first direct measurements of superfluid density, ns(T) \propto λ-2(T), in films of Fe-pnictide superconductors. The magnetic penetration depth, λ(0), in our epitaxial…
Conductance asymmetry in point-contacts on epitaxial thin films of Ba(FeCo)As
Manan Mehta, Goutam Sheet, D. A. Dikin +8
Point-contact spectroscopy is a powerful tool for probing superconductors. One of the most common observations in the point-contact spectra on the recently discovered ferropnictide…
Phase-incoherent superconducting pairs in the normal state of Ba(FeCo)As
Goutam Sheet, Manan Mehta, D. A. Dikin +8
The normal state properties of the recently discovered ferropnictide superconductors might hold the key to understanding their exotic superconductivity. Using point-contact spectro…
