MULTILAYER CERAMIC HETEROSTRUCTURE WITH MAGNETOELECTRIC EFFECT AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2013 - IPC H01L41/83 H01L41/22 

FIELD: physics.

SUBSTANCE: invention relates to making magnetoelectric converters used as a base for magnetic field sensors, microwave electronic devices, for magnetoelectric information recording technology and for electromagnetic energy and vibration energy storages. The method involves forming a stack of alternating magnetostrictor and piezoceramic layers. Said stack is formed in three steps: first, electroconductive contacts are deposited on the entire surface of magnetostrictors; all surfaces of magnetostrictors and piezoceramic, except end surfaces, are coated with a layer of electroconductive epoxy adhesive, after which a stack of alternating magnetostrictor and piezoceramic layers is formed. The layers are joined by pressing at temperature of 60-100°C and excess pressure of (1.3-2.6)·10⁵ Pa. The multilayer ceramic heterostructure contains 9-11 magnetostrictor and piezoceramic layers. The piezoeceramic layer has thickness of 0.10-0.13 mm and the magnetostrictor layer has thickness of 0.25-0.30 mm.

EFFECT: low power consumption and high sensitivity.
