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…
Magnetic Fingerprints in Superconducting AuIn Cylinders
Yu. Zadorozhny, D. R. Herman, Y. Liu
Reproducible, sample-specific magnetoresistance fluctuations (magnetic fingerprints) were observed in the low-temperature part of the superconducting transition regime of hollow Au…
Selection Rule in Josephson Coupling between In and Sr2RuO4
R. Jin, Y. Liu, Z. Q. Mao +1
We have studied the Josephson coupling between a conventional s-wave superconductor (In) and Sr2RuO4 and found that the coupling is allowed in the in-plane direction, but not along…
Observation of Magnetic Fingerprints in Superconducting Au_0.7In_0.3 Cylinders
Yu. Zadorozhny, D. R. Herman, Y. Liu
Reproducible, sample-specific magnetoresistance fluctuations (magnetic fingerprints) have been observed experimentally in the low-temperature part of the superconducting transition…
