Nano-scale visualization of magnetic vortices in metal nanoparticles
Satoko Toyama, Yoshiki O. Murakami, Ayako Nishikawa +4
Magnetic vortices in individual nanoparticles are fundamental spin structures that govern the properties of next-generation magnetic devices and biomedical applications. However, d…
Three-Dimensional Atomic-Scale Structural Transformation in a SrTiO3 Grain Boundary
Xiaoyue Gao, Jiake Wei, Bo Han +9
Grain boundaries (GBs) in complex oxides play critical roles in governing their functional properties, which are intrinsically linked to their three-dimensional (3D) atomic configu…
Switchable Polarization in an A-site Deficient Perovskite through Vacancy and Cation Engineering
Suguru Yoshida, Olivier Hernandez, Jinsuke Miyake +7
While defects are unavoidable in crystals and often detrimental to material performance, they can be a key ingredient for inducing functionalities when tailored. Here, we demonstra…
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-…
ARIM-mdx Data System: Towards a Nationwide Data Platform for Materials Science
Masatoshi Hanai, Ryo Ishikawa, Mitsuaki Kawamura +16
In modern materials science, effective and high-volume data management across leading-edge experimental facilities and world-class supercomputers is indispensable for cutting-edge…
