Electro-mechanical-magnetic coupling in multiferroic heterostructures:phase-field modeling and device applications


Jiamian Hu;Zheng Li;Longqing Chen;Cewen Nan;


<正>We theoretically study the electro-mechanical-magnetic coupling, also known as the converse magnetoelectric effect,in layered magnetic /ferroelectric heterostructures.We obtain electric-voltage induced changes in both the macroscopic magnetization and magnetic domain structures.Based on phase-field simulations,we proposed a new device concept for a strain-mediated magnetoresistive random access memory(SM-RAM).The proposed
