A brief overview of the deposition and properties of YBa2Cu3O7 (YBCO)
based heterostructures is presented. Emphasis is placed on the assessm
ent of the deposition process and the properties of practical thin fil
ms and heterostructures of layered oxides. Besides a reference to the
literature we present our recent results concerning deposition, struct
ural and magnetic properties of YBa2Cu3O7/RE(1-x)A(x)MnO(3) (YBCO/REMO
) heterostructures.
