摘要：
Grain textured surfaces of large YBa2Cu3O7-δ disks, fabricated by uniaxial pressing, show significant positional variation of texture, oxygen content, CuO impurity phase and the imaginary part of the magnetic susceptibility. Correlations between these measured properties have been determined and reasons for the observed variations given. These inhomogeneities indicate that, in most cases, quoted values for material properties properties must be treated as average values only. © 1990.
