    摘要: An improved magnetoelectric composite which incorporates LaSrMn or LaCaMn oxides as a magnetostrictive composition are described. The magnetostrictive composition preferably has the formula La0.7Sr0.3MnO3 or La0.7Ca0.3MnO3. The composites preferably have a magnetostrictive layer joined to a piezoelectric layer. The composites are useful for sensors, read-heads, storage media and high frequency transducer devices.

    摘要: Magnetoelectric multilayer composites comprising alternate layers of a bimetal ferrite wherein one of the metals is zinc and a piezoelectric material for facilitating conversion of an electric field into a magnetic field or vice versa. The preferred composites include cobalt, nickel, or lithium zinc ferrite and PZT films which are arranged in a bilayer or in alternating layers, laminated, and sintered at high temperature. The composites are useful in sensors for detection of magnetic fields (10); sensors for measuring rotation speed, linear speed, or acceleration; read-heads in storage devices by converting bits in magnetic storage devices to electrical signals; magnetoelectric media for storing information; and high frequency devices for electric field control of magnetic devices or magnetic field control of electric devices.
