E-field control of magnetization and susceptibility of AFE-based YIG/PLZST heterostructure
Résumé
The magnetoelectric properties of a laminated heterostructure consisting of ferromagnetic yttrium iron garnet (YIG) film and antiferroelectric (Pb0.97La0.02) (Zr0.6Sn0.3Ti0.1)O3 (PLZST) ceramic is, for the first time, reported in this work. The electric-field-controlled susceptibility, a shift of the coercive magnetic field and magnetization variations are demonstrated in YIG/PLZST multiferroic heterostructure. A large variation of the relative magnetic susceptibility is observed, practically 33% at a low magnetic field of 10 Oe. A sharp reduction of magnetization occurs at the antiferroelectric-ferroelectric phase transition field of PLZST ceramic. Thus the converse magnetoelectric coefficient peaks at the switching field and the maximum can reach 11.6 × 10 −8 s/m without bias magnetic field. These features indicate that antiferroelectric materials can also be alternative candidates to combine with ferromagnetic materials for magnetoelectric tunable devices.
