摘要	YBa2Cu4O8/La0.67Ca0.33MnO3/YBa2Cu4O8 (YBCO/LCMO/YBCO) trilayer films were prepared by magnetron facing-target sputtering. For the first time, the oscillatory behaviour of superconducting transition temperature T-C,T-ON with the thickness of LCMO (d(L)) has been observed. The strongest nonmonotonic information in the TC,ON-dL curves appears clearly when d(L) is larger than the critical thickness d(L)(CR). The metal semiconductor transition temperature can only be detected at dL > d(L)(CR). The dependence on the ferromagnetic spacer layer in YBCO/LCMO/YBCO systems suggests strongly the interplay of ferromagnetic and superconducting couplings.
