Title: Vortex lattice dynamics in DyBa{sub 2}Cu{sub 3}O{sub 7}/(Sr{sub 1{minus}{ital x}}Ca{sub {ital x}})RuO{sub 3} multilayers

Abstract

We have investigated vortex dynamics in DyBa{sub 2}Cu{sub 3}O{sub 7}/(Sr{sub 1{minus}{ital x}}Ca{sub {ital x}})RuO{sub 3} multilayers in parallel and perpendicular applied magnetic fields. In both configurations, we have measured activation energies {ital U} for flux motion and determined vortex coupling through either ferromagnetic (SrRuO{sub 3}) or nonmagnetic (CaRuO{sub 3}) barriers. Coupled motion of pancake vortices belonging to different DyBa{sub 2}Cu{sub 3}O{sub 7} layers occurs for nonmagnetic barriers (CaRuO{sub 3}) as large as several hundreds of A . In the case of ferromagnetic barriers (SrRuO{sub 3}), 50 A was found to be sufficient to decouple the vortices between the barrier. The ferromagnetism present in the SrRuO{sub 3} barrier is believed to be responsible for such behavior. {copyright} {ital 1996 The American Physical Society.}
