Popis: The high-temperature superconductors are layered materials whose properties are related to the stacking sequence of the various metal-oxide layers. This paper describes recent efforts to modify artificially this stacking sequence and thus to produce new superlattice structures. In particular, we have grown YBa 2 Cu 3 O 7 /PrBa 2 Cu 3 O 7 superlattices with modulation wave lengths as small as 24 A. We review here recent experiments on this system and we demonstrate how these superlattices can be used to study the role of anisotropy in the thermally activated flux creep behaviour of the high-temperature superconductors.
