Existence of two electronic states in Sr4Ru3O10 at low temperatures
Zhuan Xu, Xiangfan Xu, Rafael S. Freitas +7
We report measurements on in-plane resistivity, thermopower, and magnetization as a function of temperature and magnetic fields on single crystalline Sr4Ru3O10 grown by the floatin…
Observation of a mixed pairing state in Ru microdomains embedded in
Z. Long, C. Andreou, Z. Q. Mao +3
We report first measurements on tunneling into the {\it interior} of a Ru microdomain embedded in bulk chiral p-wave superconductor SrRuO. The junctions were prepared b…
"Super weakly" coupled superconductivity in ultrathin superconductor-normal-metal bilayers
Zhenyi Long, M. D. Stewart, James M. Valles
Tunneling measurements of the temperature dependence of the electronic density of states (DOS) of ultrathin bilayers of Pb and Ag reveal that their superconducting energy gap, $Δ(T…
Magnetic Flux Periodic Response of Nano-perforated Ultrathin Superconducting Films
M. D. Stewart, Zhenyi Long, James M. Valles +2
We have patterned a hexagonal array of nano-scale holes into a series of ultrathin, superconducting Bi/Sb films with transition temperatures 2.65 K 5 K. These regular p…
Early stage morphology of quench condensed Ag, Pb and Pb/Ag hybrid films
Zhenyi Long, James M. Valles
Scanning Tunneling Microscopy (STM) has been used to study the morphology of Ag, Pb and Pb/Ag bilayer films fabricated by quench condensation of the elements onto cold (T=77K), ine…
