Oct 01, 2003 In this paper, a part of the results of mechanical and thermal property measurements on various melt-textured high T c bulk materials, studies of magnetizing techniques and magnetic field generation by them, and an experiment of high gradient magnetic separation HGMS by bulk superconducting magnets are reported. 2.
We have developed new asymmetric high-Tc superconducting Bi1.85Pb0.35Sr1.9Ca2.1Cu3.1O10 membrane with high efficiency for nitrogen separation from air. This membrane with controlled pore structure can be prepared by the electrophoretic deposition of colloidal Bi1.85Pb0.35Sr1.9Ca2.1Cu3.1O10 nanosheets on the substrate pellet. The presence of
Aug 01, 1990 High Tc superconductors and critical current measurement L.R Goodrich and S.L. Bray Center for Electronics and Electrical Engineering, National Institute of Standards and Technology, Boulder, CO 80303, USA Received 17 January 1990 With the introduction of high Tc superconductors, a number of problems associated with critical current, Ic, measurement have arisen.
Dec 20, 2001 There is a long-standing debate about whether spincharge separation is the root cause of the peculiar normal-state properties and high superconducting transition temperatures of the high-Tc ...
Jan 01, 2012 Type II superconductors have two critical fields H c1 and H c2 . H c1 is the field at which flux starts to penetrate the superconductor and H c2 is the field at which superconductivity is lost entirely. H c2 depends on the temperature but generally is very high in high temperature superconductors such as YBCO or its REBCO analogues, up to 100 T by some reports.

Sep 11, 2018 Superconducting materials find practical application in one of three broad forms wires and tapes, thin films and bulks. Since the arrival of high-temperature superconducting HTS materials 30 years ago, and more recently the discovery of superconductivity in MgB 2 and iron-based materials, progress in bulk materials has been somewhat overshadowed by the considerable effort required to ...

Iron-based superconductors exhibit a number of properties attractive for applications, including low anisotropy, high upper critical magnetic fields H c2 in excess of 90 T and intrinsic critical current densities above 1 MA cm 2 0 T, 4.2 K.It was shown recently that bulk iron-pnictide superconducting magnets capable of trapping over 1 T 5 K and 0.5 T 20 K can be fabricated with fine ...

OHFeSe5,6, high-T c superconductivity with T c above 3040K has been successfully achieved. More surprisingly, when a single unit-cell FeSe lm is fabricated on the SrTiO 3 substrate, its T c can be raised up to 65100K7,8. Here we refer these high-T c superconductors derived directly from FeSe as
Sep 01, 1996 We report on the assembly, characterization and operation of a high temperature superconducting HTS magnetic separator.
