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-…
