E-field control of magnetization and susceptibility of AFE-based YIG/PLZST heterostructure.

• E-field controlled magnetism in an AFE-based YIG/PLZST heterostructure shows potentials for creating device functionalities. • A large CME coefficient (11.6 × 10−8 s/m) is obtained at 0 Oe. • E-field tuning of susceptibility variation can reach 33% at a low magnetic field of 10 Oe. The magnetoelectric properties of a laminated heterostructure consisting of ferromagnetic yttrium iron garnet (YIG) film and antiferroelectric (Pb 0.97 La 0.02) (Zr 0.6 Sn 0.3 Ti 0.1)O 3 (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-ferroelectic 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. [ABSTRACT FROM AUTHOR]
