Texture processing of extruded YBa2Cu3O6+x wires by zone melting

Abstract

Zone melting has been used to produce texture in extruded YBa2Cu3O6+x wires. By controlling the directional solidification of the molten zone, oriented structures are produced that show a large magnetic hysteresis at 77 K compared to unaligned extruded YBa2Cu3O6+x wires. A magnetization critical current density of 1.8 × 104 A/cm2 in an applied field of 20 kOe has been achieved.
