    摘要: A magnetoresistive sensor includes a plurality of multilayered magnetoresistive films arranged in parallel. Each multilayered magnetoresistive film includes at least one pinned ferromagnetic layer and at least one free magnetic layer. Reversion of magnetization of the pinned ferromagnetic layer is pinned, whereas the vector of magnetization of the free ferromagnetic layer freely reverses in response to an external magnetic field. The vectors of magnetization of the pinned ferromagnetic layers in two adjacent multilayered magnetoresistive films are substantially antiparallel to each other.

    摘要: The present invention provides a method of producing a glassy alloy which has soft magnetism at room temperature and high resistivity and which can be easily obtained in a bulk shape thicker than an amorphous alloy ribbon obtained by a conventional melt quenching method. In this method, a melted metal having a supercooled liquid temperature width .DELTA.T.sub.x of 35.degree. C. or more, which is expressed by the equation .DELTA.T.sub.x =T.sub.x -T.sub.g (wherein T.sub.x indicates the crystallization temperature, and T.sub.g indicates the glass transition temperature), is sprayed on a cooling body under movement to form a ribbon-shaped glassy alloy material; and the glassy alloy is then heat-treated by heating at a heating rate of 0.15 to 3.degree. C./sec and then cooling.

    摘要: A soft magnetic alloy thin film includes a fine crystalline phase and an amorphous phase. The fine crystalline phase includes an average crystalline grain size of 10 nm or less in diameter and has body-centered cubic structure mainly composed of Fe. The amorphous phase has a nitrogen (N) compound as the main composition and occupies at least 50% of the structure of the thin film. An element M is incorporated at least in the amorphous phase, and includes at least one element selected from the group consisting of Ti, Zr, Hf, V, Nb, Ta, W, and rare earth metal elements. A plane-type magnetic device is made using this thin film.
