摘要：

Quantitative magnetooptical measurements have been used to investigate the critical current density in epitaxially grown bilayers of La1/3Ca1/3MnO3 and YBa(2)Cu(3)o(7-delta). The experiments show that the current density in the superconducting film is strongly supressed due to the adjacent ferromagnetic layer. Additionally it is found that the magnetization state of the ferromagnet influences the critical current density in the superconductor. (C) 2004 Elsevier B.V. All rights reserved.
