Structural changes of superconducting YBa2Cu4O8 under high pressure
Yuh Yamada,James D. Jorgensen,Shiyou Pei,Philip Lightfoot,Yasuharu Kodama,Takehiko Matsumoto,Fujio Izumi +6 more
TL;DR: In this article, structural changes in YBa2Cu4O8 have been studied as a function of pressure using TOF neutron powder diffraction with a sample in a helium-gas pressure cell.
Journal ArticleDOI
Superconducting and mechanical properties of YBCO-Ag composite superconductors
TL;DR: In this paper, measurements of electrical properties and X-ray structural analysis were made for sintered composite materials prepared by mixing the powders of the ceramic superconductor YBa2Cu3O7−x (YBCO) and the pure metal element M with with Ni, Cu and Ag at 50 vol% proportions.
Journal ArticleDOI
High-Temperature Superconducting Motor Using Y-Ba-Cu-O Bulk Magnets
Yoshitaka Itoh,Yousuke Yanagi,Masaaki Yoshikawa,Tetsuo Oka,Shintaro Harada,Tsutomu Sakakibara,Yuh Yamada,Uichiro Mizutani +7 more
TL;DR: In this article, a DC motor equipped with melt-processed Y-Ba-Cu-O (YBCO) superconductors as field magnets was constructed and the maximum output power was 940 W when the YBCO bulks were cooled to 65 K.
Journal ArticleDOI
Critical current density and mechanical strength of YBa2Cu3O7-δ superconducting composites containing Zr, Ag and Y2BaCuO5 dispersions by melt-processing
Tetsuo Oka,Yoshitaka Itoh,Yosuke Yanagi,Hidehiko Tanaka,S. Takashima,Yuh Yamada,Uichiro Mizutani +6 more
TL;DR: In this article, the critical current density and the flexural strength α max of YBa 2 Cu 3 O 7−δ composite superconductors were measured and the microstructure analysis revealed that the Y 2 BaCuO 5, Ag and BaZrO 3 were finely dispersed in the matrix.
Journal ArticleDOI
Preparation of melt-textured NdBa2Cu3Oy bulk with Nd4Ba2Cu2O10 addition
Atsushi Takagi,Takeo Yamazaki,Tetsuo Oka,Yosuke Yanagi,Yoshitaka Itoh,Masanobu Yoshikawa,Yuh Yamada,Uichiro Mizutani +7 more
TL;DR: In this article, the NdBa 2 Cu 3 O y (Nd123) bulk superconductor, to which Nd 4 Ba 2 Cu 2 O 10(Nd422) particles were intentionally added, was prepared through the so-called MMTG process in Ar (99% purity) flowing atmosphere at an ambient pressure.
