Imaging and characterization of spontaneous vortices in a proximity-induced superconductor
Iku Nakaaki, Kotaro Taki, Mio Nomura +11
Observation of spontaneous symmetry breaking is crucial for understanding continuous second-order phase transitions from disordered to ordered states, which often leads to the form…
Establishment of global phase coherence in a highly disordered fractal MgO/MgB2 nanocomposite: Roles of interface, morphology and defect
Iku Nakaaki, Aoi Hashimoto, Shun Kondo +11
Recently, we have reported that a highly disordered fractal MgO/MgB2 nanocomposite exhibits bulk-like superconducting properties with isotropic pinning, showing an excellent phase-…
Strong phase coherence and vortex matter in a fractal system with proximity-induced superconductivity
Nanami Teramachi, Aoi Hashimoto, Iku Nakaaki +10
The proximity effect in normal/superconductor heterostructures is an intriguing phenomenon in that the normal side takes on the properties of a superconductor with an induced gap.…
Superconductors that do not expel magnetic flux
Y. Tanaka, H. Yamamori, T. Yanagisawa +2
An ultrathin superconducting bilayer creates a coreless fractional vortex when only the second layer has a hole. The quantization is broken by the hole, and the normal core disappe…
Anomalous flux quantization and formation of dipole-flux state in a multiply-connected high-Tc NdBa2Cu3O7-d superconductor
K. S. Yun, I. Iguchi, S. Arisawa +1
High-resolution scanning superconducting quantum interference device (SQUID) microscopy was used to study the flux quantization phenomenon in multiply-connected anisotropic high-Tc…
Hot spots and waves in Bi2Sr2CaCu2O8 intrinsic Josephson junction stacks -a study by Low Temperature Scanning Laser Microscopy
H. B. Wang, S. Guénon, J. Yuan +6
Recently, it has been shown that large stacks of intrinsic Josephson junctions in Bi2Sr2CaCu2O8 emit synchronous THz radiation, the synchronization presumably triggered by a cavity…
