Abstract: Ferroelectric solid solutions simultaneously containing lead, iron, niobium, bismuth, zirconium, lanthanum, and oxygen are synthesized and sintered at temperatures lower than 1,000* C. Polycrystalline layers and films of such compositions are prepared by radio-frequency sputtering, electron beam evaporation, chemical spray deposition, or centrifuge deposition. Layers of such compositions only a few microns or fractions of a micron thick when on a conductive substrate are used as nonlinear elements in logic and memory devices.

Abstract: CORROSION RESISTANT MAGNETIC RECORDING MEDIA A thin film magnetic recording medium for deposition on a record carrier includes a ferromagnetic alloy containing iron, cobalt and chromium. The ferromagnetic alloy consists of from 0-55% cobalt, from 8-22% of chromium with the remainder iron. The preferred range of chromium is from 10-18%. The magnetic recording layer is vacuum deposited over an extended portion of a record carrier for storing information which is represented by the spatial distribution of magnetic transitions in the magnetic layer. The iron-cobalt-chromium or iron-chromium composition according to this invention, gives the best magnetic properties consistent with excellent corrosion resistance. SA976033
