Additions of BaSnO3 have been made to YBa2Cu3O6+ x/Y2BaCuO5 composite wires to
examine its potential for improving solidification processing and enhancing pinning. Zone
melting has been used to produce texture in extruded YBa2Cu3O6+ x (Y‐123) wires with
Y2BaCuO5 (211) and BaSnO3 additions. BaSnO3 additions markedly improve the
magnetization properties over similarly textured Y‐123 or Y‐123+ 211 wires in low fields, but
do not show a noticeable improvement at higher fields (≳ 2 T). Microstructural effects of …
