Experimental Study of High Temperature Superconductors through Substitutionte the role of a particular constituent of a superconductor. We will review the results of substitution for the Cu sites in YBa.Cu.O.. New results of cation substitution for the La and Cu sites in La.Sr.CuO. will be presented and discussed.

Electron Microscopic Studies of Oxygen Ordering Phenomena in YBa2Cu3O7-δlso along the c direction. Its spatial structure is described. The .structure is shown to be presumably due to deformation modulation rather than to oxygen ordering. The results are compared with the theoretical predictions based on an Ising model.

Spin and Hole Dynamics in Doped Anisotropic Heisenberg Antiferromagnets because likely provide a good realization of a low-dimensional spin-1/2 Heisenberg antiferromagnet. Although the ability of the two dimensional Heisenberg model to fully explain the magnetic properties of the layered metal oxides has not been established,. its study has became one of the most active fields of research in solid state physics..

ld April 18-21, 1989 at the International Centre for Theoretical Physics, Trieste, Italy. It was recognized very early in the field of ceramic superconductors that oxygen plays a crucial role as far as the physical properties of these ma- terials are concerned. The preparation requires special heati
