Thin-film transformer utilizing superconductive components |
摘要 |
Thin-film transformer, for example suitable for use in a thin-film magnetic head, comprising a magnetic yoke composed of two magnetically permeable thin layers 3 and 5 and a primary turn constituted by an electrically conducting thin layer 13 and a secondary turn constituted by an electrically conducting thin layer 15. A thin layer 21 of a superconducting material is provided between the layer 3 and the said turns, or the turns are closely fitted together and made of a superconducting material themselves.
