Anisotropy in an Oriented Ba2YCu3O7 Superconductor

A highly oriented Ba2YCu3O7 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.

Description
Summary:A highly oriented Ba2YCu3O7 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.
