Melt textured Y123 bulk and thick film

YBa 2Cu 3O 7−δ - 25mol%Y 2BaCuO 5 bars and thick films have been melt textured using a stationary furnace with a temperature gradient of 3 or 6 °C/cm. Samples are heated above the peritectic reaction temperature and quenched to just above the solidification temperature and then slowly cooled below t...

Description
Summary:YBa 2Cu 3O 7−δ - 25mol%Y 2BaCuO 5 bars and thick films have been melt textured using a stationary furnace with a temperature gradient of 3 or 6 °C/cm. Samples are heated above the peritectic reaction temperature and quenched to just above the solidification temperature and then slowly cooled below the solidification temperature. All bar shaped samples consist of 2∼5 mm grains though the grain orientations strongly depend on the heat treatment conditions. The bar shows the maximum J c of above 3000 A/cm 2, whereas the maximum J c of 200 A/cm 2 and T c zero of 88 K are obtained for the thick film on (100) LaAlO 3 single crystal.
