It is found that the peak values of the imaginary component of ac susceptibility x"(max) versus H-ac trace a valley for the orientation where applied field H-a perpendicular to wide face of the tape total. We note that the observation of the valley depends on various parameters such as field dependence parameter n in the critical current density, in the simple power law expression j(c)- alpha(T)/B-n, choice of the bias field H-dc together with selected ac field amplitudes H-ac, and dimension and geometry of sample studied. Our calculations based on critical state model with j(c) - alpha(1 - T/T-cm)(p)/B-n using the fitting parameters of n - 0.25, p- 2.2, T-cm- 108 K gives quite good results to compare the experimental and calculated curves.</dc:description> <dc:identifier>https://aperta.ulakbim.gov.trrecord/43705</dc:identifier> <dc:identifier>oai:zenodo.org:43705</dc:identifier> <dc:rights>info:eu-repo/semantics/openAccess</dc:rights> <dc:rights>http://www.opendefinition.org/licenses/cc-by</dc:rights> <dc:source>EUROPEAN PHYSICAL JOURNAL-APPLIED PHYSICS 80(3)</dc:source> <dc:title>Effect of dc field on ac-loss peak in a commercial Bi:2223/Ag tape</dc:title> <dc:type>info:eu-repo/semantics/article</dc:type> <dc:type>publication-article</dc:type> </oai_dc:dc>
