Cu-O sublattice

The fact that Tc is essentially unchanged by replacement of Y with the magnetic rare earth elements points to the Cu-O sublattice as the source of the superconducting properties of Y,Ba2Cu309 y. Mixtures of rare earths or alkaline earths (2,13) also do not affect Tc, again emphasizing the key role of the Cu-O sublattice. [Pg.269]

The Cu-O sublattice is the source of the superconducting behavior. The ordering of this sublattice is very dependent on the processing. [Pg.270]

The low dimensional electronic structure of the Cu-O sublattice appears to be a general and important feature in all of the perovskite superconductors. [Pg.270]
