摘要：

A highly oriented Ba//2YCu//3O//7 ceramic disk was prepared with the c axis perpendicular to the flat faces. The use of high pressures during cold-pressing tends to enhance the orientation of the fired sample. A nitric acid procedure for forming the material produces a powder which orients most readily. Magnetic measurements show that the critical current is larger in the layers perpendicular to the pressing direction.
