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-…

Atomic-Scale Observation of Moire potential in Twisted Hexagonal Boron Nitride Layers by Electron Microscopy
Rina Mishima, Takuro Nagai, Hiroyo Segawa +2
Moire superlattices (MSLs) are an emerging class of two-dimensional functional materials whose electronic states can be tuned by the twist angle between two van der Waals layers an…
