Universidad de Zaragoza (orcid)0000-0001-7056-0546 Effect of postannealing process on Bi2Sr2.1Ca 0.9Cu2O8+δ textured superconductors 2013 Access copy available to the general public Unrestricted Bi-2212 samples prepared by the classical solid-state method have been grown from the melt using the Laser Floating Zone (LFZ) method. They have shown good grain alignment and transport critical current densities (J c ). After postannealing processes designed to produce the Bi-2212 phase controlled decomposition, J c values have been increased in an important manner. Maximum values have been achieved when samples were thermally treated at 680 °C for 168 h with improvements around 80 %, compared with the original textured samples. The results clearly indicate that postannealing processes, when adequately controlled, produce the formation of effective pinning centers which are responsible for the increase in the measured J c values. info:eu-repo/grantAgreement/ES/DGA/T12 info:eu-repo/grantAgreement/ES/DGA/T87 info:eu-repo/grantAgreement/ES/MICINN/MAT2008-00429 info:eu-repo/grantAgreement/ES/MINECO/MAT2011-22719 info:eu-repo/grantAgreement/ES/UZ/UZ2011-TEC-03 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 0.93 2013 PHYSICS, CONDENSED MATTER 53 / 67 = 0.791 2013 Q4 T3 PHYSICS, APPLIED 102 / 135 = 0.756 2013 Q4 T3 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Madre, M.A. Universidad de Zaragoza (orcid)0000-0002-0794-3998 Rasekh, S.
