Description

Using an electron diffraction technique, the thicknesses of the (nonorthorhombic) twin boundary layers were measured for pure and alloyed YBa2(Cu/sub 1-//sub x/M/sub x/)3O/sub 7-//sub δ/. Boundary thickness varied from ∼0.7 nm for M = Ni, x = 0.02, and δ≅0 to ∼2.6 nm for M = Al, x = 0.02, and δ≅0, while it was ∼1.0 nm for a pure YBa2Cu3O7. High-resolution transmission electron imaging of similar specimens supports the existence of such twin boundary layers
