Ichiro Shigaki,Katsuki Kitahama,Kazuyuki Shibutani,Seiji Hayashi,Rikuo Ogawa,Yoshio Kawate,Tomoji Kawai,Shichio Kawai,Masahide Matsumoto,Junji Shirafuji +9 more
TL;DR: In this article, a single crystal preparation of the Bi2.0Oy superconductor by the travelling solvent floating zone method has been performed with the intention of obtaining large single crystals and improving the superconductive transition temperature, Tc.
Journal ArticleDOI
Development of 1 GHz superconducting NMR magnet at TML/NRIM
TL;DR: In this paper, a 1 GHz superconducting NMR magnet is developed at the Tsukuba Magnet Laboratory of the National Research Institute for Metals (NIRIMA), which will consist of two parts: the outer magnet of LTS coils is designed to generate a field of 21.1 T (900 MHz) in persistent current mode.
