Number of pages 360 Language eng - English Country HR - Croatia Keywords LRE-123 ; vortex pinning enhancement ; nanoscale precipitates ; levitateion at liquid oxygen temperature Subject RIV BM - Solid Matter Physics ; Magnetism R&D Projects ME10069 GA MŠMT - Ministry of Education, Youth and Sports (MEYS) CEZ AV0Z10100520 - FZU-D (2005-2011) Annotation A survay is given on the role of nanoscale precipitates of various compounds working in the bulk of various LRE-Ba_2 Cu_3 O_y (LRE-123), where LRE stands for Light Rare Earth, LRE=Nd,Sm, Eu, Gd, as a pinning agent. Minimization of the particles and bringing their size to the range of vortex core size enables such a critical current enhancement that the material can be used as a superconducting supermagnet up to vicinity of critical temperature (in the given compounds it means cooling by liquid oxygen). These conditions moreover extend up to high magnetic fields. Workplace Institute of Physics Contact Kristina Potocká, potocka@fzu.cz, Tel.: 220 318 579 Year of Publishing 2012
