Abstract
The presence of applied magnetic field H on superconductor material causes the vortex movement and finally the energy dissipation, so that the materials have a low critical current density (Jc). A flux pinning is required to hold the vortex movement. We study the existence of flux pinning enhancement on superconductor YBa{sub 2}Cu{sub 3}O{sub 7x} system from sintering process (YBaCuO-sintering) to melt texture growth process (YBaCuO-MTG). The high pinning force density Fp is affected by material inhomogeneity in the form of grain boundary. crystal defect in the form of material impurity, experiment temperature very low, and high applied magnetic field H. Fp maximum at T = 5 K for the YBaCuO-sintering and YBaCuO-MTG samples are 1.42 x 10{sup 8} Nm{sup 3} (H 17 k Oe) and 7.39 x 10{sup 9} Nm{sup -3} (H = 14 k Oe), respectively. Jc maximum for the YBaCuO sintering and YBaCuO-MTG samples are 1.78 x 10{sup 4}A.cm{sup -2} and 5.76 x 10. A.cm{sup -2}, respectively. Jc maximum was obtained at Fp optimum. By controlling and optimizing Fp, it is expected that Jc increase.
