Superlattices of YBa{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}/Y{sub {ital y}}Pr{sub 1{minus}{ital y}}Ba{sub 2}Cu{sub 3}O{sub 7{minus}{ital x}}({ital y}=0.8 and 0.0) have been successfully grown {ital in} {ital situ} on MgO and LaAlO{sub 3} by using a multitarget pulsed laser deposition system. Satellite peaks have been observed in x-ray diffraction for the superlattices with modulation wavelengths from about few tens of angstroms to few hundred angstroms. The x-ray diffraction measurements also indicate that the multilayers have {ital c} axis normal to the substrates. Good crystallinity has been observed in the superlattices with He ion backscattering minimum yields of about 10%, indicating highly oriented growth. The presence of a periodic layer structure was further confirmed by the observation of composition oscillations in these structures by secondary-ion mass spectrometry.
