Effect of Cu doping on superconductivity in TaSe: Relationship between superconductivity and induced charge density wave
Atsushi Nomura, Kazuhiko Yamaya, Shigeru Takayanagi +2
By measuring the temperature dependence of the resistance, we investigated the effect of Cu doping on superconductivity (SC) in Cu-doped TaSe in which the charge density wave (…
Co-appearance of superconductivity and ferromagnetism in a CaRuO nanofilm crystal
Hiroyoshi Nobukane, Kosei Yanagihara, Yuji Kunisada +7
By tuning the physical and chemical pressures of layered perovskite materials we can realize the quantum states of both superconductors and insulators. By reducing the thickness of…
Superconducting networks with the proximity effect
S. Tsuchiya, S. Tanda
We report on the first observation of a novel type of superconducting proximity network using a superconductor-normal metal bilayer. Little-Parks oscillation measurements show that…
Discovery of parity-violating Majorana fermions in a chiral superconductor Sr2RuO4
Hiroyoshi Nobukane, Akiyuki Tokuno, Toyoki Matsuyama +1
We found parity-violating Majorana fermions in a chiral superconductor Sr2RuO4. The current-voltage curves show an anomalous behavior: The induced voltage is an even function of th…
Duality Breaking of Vortex Configuration in a Hierarchical Honeycomb Network
S. Tsuchiya, T. Toshima, H. Nobukane +2
We report measurements of Little-Parks oscillation on the hierarchical honeycomb-superconducting network for investigating possible effects of hierarchical structure in terms of sp…
Parity Violation in a Single Domain of Spin-Triplet Sr2RuO4 Superconductors
H. Nobukane, K. Inagaki, K. Ichimura +8
We observed an unconventional parity-violating vortex in single domain Sr2RuO4 single crystals using a transport measurement. The current-voltage characteristics of submicron Sr2Ru…
