We report on the fabrication of La0.7Sr0.3MnO3/YBa2Cu3O7, (LSMO/YBCO) multi
layers grown by high pressure de sputtering on LaAlO3 substrates. X-ray dif
fraction analysis of the single and bilayer films confirms c-axis epitaxial
growth; superlattice structure shows second order satellite peaks. Magneti
c moment measurements show both superconducting and ferromagnetic order bel
ow the superconducting transitions T-c0 Superconducting transitions for a s
eries of multilayers with fixed YBCO thickness d(YBCO) = 5.8 nm and increas
ing thickness of LSMO layers d(LSMO) from 1.2 to 3.6 nm show monotonic decr
ease of T-c0.
