摘要：

Structural, magnetic, and superconducting properties of ferromagnetic/superconducting multilayers of Fe4N/NbN are explored for a variety of thickness combinations. The superconducting properties show that 11 Angstrom ferromagnetic layers are sufficient to decouple the superconducting layers and to yield anisotropic behavior. The upper critical field data are well described by theory for ferromagnetic/superconducting multilayers. This analysis yields an interfacial parameter which characterizes the electron scattering at the ferromagnetic/superconducting boundary.
