Magnetic shielding characteristics of hybrid shields consisting of second generation high-temperature superconducting tapes and ferromagnetic materials are presented. Shields with multiple layers with several combinations of superconducting and ferromagnetic materials showed interesting patterns. Shielding factors as high as 95% are observed for three-layer hybrid shielding structures. The data presented offers new ways to achieve the required shielding factors in a given application with minimal use of expensive superconductors.
