Abstract :
Multilayer deposition for the creation of a well-defined grain boundary, based on different in-plane orientations of c-axis oriented thin YBa/sub 2/O/sub 2/Cu/sub 3/O/sub 7- delta / layers on a single substrate, has been performed on three different kinds of substrates: (1102)-oriented Al/sub 2/O/sub 3/,
