Properties of epitaxially grown A-axis oriented YBa/sub 2/Cu/sub 3/O/sub 7-x/-PrBa/sub 2/Cu/sub 3/O/sub 7-y/ heterostructures

Multilayer structures of YBa/sub 2/Cu/sub 3/O/sub 7-x/-PrBa/sub 2/Cu/sub 3/O/sub 7-y/ were prepared, using pulsed laser deposition, with the a-axis oriented normal to the surface of a variety of
