Low Temperature Metallic State of Ultrathin Films of Bismuth
L. M. Hernandez, Kevin A. Parendo, A. M. Goldman
Measurements of resistance vs. temperature have been carried out on a sequence of quench-condensed ultrathin films of amorphous bismuth (a-Bi). The resistance below about 0.1K was…
Two-Phase Regime in the Magnetic Field-Temperature Phase Diagram of a Type-II Superconductor
L. L. A. Adams, Klaus Halterman, Oriol T. Valls +1
The magnetic field and temperature dependencies of the magnetic moments of superconducting crystals of have been studied. In a constant magnetic field and at temper…
Parallel Magnetic Field Induced Glass-Like Behavior of Disordered Ultrathin Films
L. M. Hernandez, A. Bhattacharya, K. A. Parendo +1
Dramatic glass-like behavior involving nonexponential relaxation of in-plane electrical conduction, has been induced in quench-condensed ultrathin amorphous Bi films by the applica…
New Universality Class at the Magnetic Field Tuned Superconductor-Insulator Transition?
N. Markovic, C. Christiansen, A. M. Goldman
The superconductor-insulator transition in ultrathin films of amorphous Bi was tuned by an applied magnetic field. A finite size scaling analysis has been carried out to determine…
