  • MULTIFERROIC NANOSCALE THIN FILM MATERIALS, METHOD OF ITS FACILE SYNTHESES AND MAGNETOELECTRIC COUPLING AT ROOM TEMPERATURE
    Publication number: 20160012951
    Abstract: Methods of producing a multiferroic thin film material. The method includes the steps of providing a multiferroic precursor solution, subjecting the precursor solution to spin casting to produce a spin cast film, and heating the spin cast film. The precursor solution may include Bi(NO3)3.5H2O and Fe(NO3)3.9H2O in ethylene glycol to produce a bismuth ferrite film. Further, the thin film may be utilized in varied technological areas, including memory devices for information storage.
    Type: Application
    Filed: October 11, 2013
    Publication date: January 14, 2016
    Applicant: NORTHROP GRUMMAN SYSTEMS CORPORATION
    Inventors: Ronald G. Pirich, Nan-Loh Yang, Kai Su, I-Wei Chu
