  • Patent number: 11501905
    Abstract: A monolithic multiferroic heterostructure fabricated using CSD (chemical solution deposition) is disclosed. The monolithic heterostructure includes a substrate, a ferromagnetic layer, a ferroelectric layer, and one or more seed layers that enhance crystallinity and promote high frequency performance.
    Type: Grant
    Filed: August 31, 2020
    Date of Patent: November 15, 2022
    Assignee: BOSTON APPLIED TECHNOLOGIES, INC.

  • Patent number: 10190045
    Abstract: A nano-composite structure comprises of an amorphous matrix with embedded nano-crystallites. The nano-crystallites are precipitated from the amorphous matrix via heat treatment of a solution mixture of metal salts or metalorganic compounds to an appropriate temperature range and with a suitable duration, or heating of a mixture of non-crystalline compounds. The nano-crystallites are self-assembled in the amorphous matrix without forming agglomerates or distinguished grain boundaries. The nano-composite structure can be used for transparent display, transparent optical ceramics, protection armor, nuclear protection, pulsed power, high voltage electronics, high energy storage system and high power microwave systems.

  • Patent number: 8124254
    Abstract: A heterostructure of multiferroics or magnetoelectrics (ME) was disclosed. The film has both ferromagnetic and ferroelectric properties, as well as magneto-optic (MO) and electro-optic (EO) properties. Oxide buffer layers were employed to allow grown a cracking-free heterostructure a solution coating method.
