Possible observation of phase separation near a quantum phase transition in doubly connected ultrathin superconducting cylinders of aluminum
H. Wang, M. M. Rosario, N. A. Kurz +4
The kinetic energy of superconducting electrons in an ultrathin, doubly connected superconducting cylinder, determined by the applied flux, increases as the cylinder diameter decre…
Observation of double resistance anomalies and excessive resistance in mesoscopic superconducting AuIn rings with phase separation
H. Wang, M. M. Rosario, H. L. Russell +1
We have measured mesoscopic superconducting AuIn rings prepared by e-beam lithography and sequential deposition of Au and In at room temperature followed by a stand…
Quantum phase transition in superconducting Au0.7In0.3 films of very low normal-state sheet resistance
M. M. Rosario, H. Wang, Yu. Zadorozhny +1
We report the observation of a quantum phase transition (QPT), tuned by a parallel magnetic field, between a superconducting and metallic state in Au0.7In0.3 films of very low norm…
Electrical transport studies of quench condensed Bi films at the initial stage of film growth: Structural transition and the possible formation of electron droplets
M. M. Rosario, Y. Liu
The electrical transport properties of amorphous Bi films prepared by sequential quench deposition have been studied in situ. A superconductor-insulator (S-I) transition was observ…
Geometrical destruction of the global phase coherence in ultrathin superconducting cylinders
Y. Liu, Yu. Zadorozhny, M. M. Rosario +3
The global phase coherence in doubly-connected superconductors leads to fluxoid quantization, allowing the superfluid velocity vs to be controlled by an applied magnetic flux. In u…
Experimental determination of superconducting parameters for the intermetallic perovskite superconductor ${\text {MgCNi}}_3
Z. Q. Mao, M. M. Rosario, K. D. Nelson +7
We have measured upper-critical-field , specific heat C, and tunneling spectra of the intermetallic perovskite superconductor MgCNi with a superconducting trans…
