Unleashing the Full Potential of Magnetoelectric Coupling in Film Heterostructures

A record‐high, near‐theoretical intrinsic magnetoelectric (ME) coupling of 7 V cm−1 Oe−1 is achieved in a heterostructure of piezoelectric Pb(Zr,Ti)O3 (PZT) film deposited on magnetostrictive Metglas (FeBSi). The anchor‐like, nanostructured interface between PZT and Metglas, improved crystallinity o...

Zusammenfassung:A record‐high, near‐theoretical intrinsic magnetoelectric (ME) coupling of 7 V cm−1 Oe−1 is achieved in a heterostructure of piezoelectric Pb(Zr,Ti)O3 (PZT) film deposited on magnetostrictive Metglas (FeBSi). The anchor‐like, nanostructured interface between PZT and Metglas, improved crystallinity of PZT by laser annealing, and optimum volume of crystalline PZT are found to be the key factors in realizing such a giant strain‐mediated ME coupling.
