dc.description.abstractIn the present study, we examine the energy dissipation mechanisms and grain boundary effects on the superconducting properties of high-T-c SmBa2Cu3O7-x samples. Sm-123 was synthesized with the top-seeded-melt-growth technique. Grain sizes, as determined by optical microscopy, ranged between 0.5 mm and 1.5 mm. Thus, each specimen, on which the electrical and magnetic measurements were carried out, contained several grains. Some of our findings are as follows: (1) the intragrain T-c is 93.5 K and the intergrain T-c is 87.5 K. Superconducting transition width is narrow and is not affected much by the magnetic field. (2) The intragrainjc is 110,000A cm(-2) while the intergrainjc is 210 A cm(-2) at 10 K. (3) The intergrain J(c) shows a secondary peak with the increase in temperature from 10 K to 30 K. The main reasons behind these observations are discussed in detail. (C) 2009 Elsevier B.V. All rights reserved.en_US
