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.…
Spontaneous vortex state in a superconductor/ferromagnet nanocomposite
Nanami Teramachi, Yusuke Seto, Takahiro Sakurai +2
The mechanism of the interplay between superconductivity and magnetism is one of the intriguing and challenging problems in physics. Theory has predicted that the ferromagnetic ord…
Magnetic correlations in the pressure-induced superconductor CrAs investigated by As nuclear magnetic resonance
Kei Matsushima, Hisashi Kotegawa, Yoshiki Kuwata +7
We report As-NMR results for CrAs under pressure, which shows superconductivity adjoining a helimagnetically ordered state. We successfully evaluated the Knight shift from t…
Macroscale three-dimensional proximity effect in disordered normal/superconductor nanocomposites
Katsuya Ueno, Nobuhito Kokubo, Satoru Okayasu +8
Recently, interest in Superconductor (S)-Normal (N) interfaces was renewed by the observation of exotic proximity effects in various systems, including S/semiconductor, S/ferromagn…
Enhancement of the superconducting transition temperature of MgB2 by proximity effect of d0 ferromagnet
Takashi Uchino, Kazuyuki Takahashi, Yuki Uenaka +9
Heterostructures of superconducting and ferromagnetic materials are of fundamental interest because of the mutual interaction of antagonistic kinds of ordering at the S-F interface…
