“…Significant progress has been made in E-field control of macroscopic magnetic properties of multiferroic heterostructures, including the magnetic anisotropy [10,11], the exchange bias [12,13], the magnetoresistance [14,15], the magnetic permeability [16], and the Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction [17], etc. In consideration of the potential applications in micro/nano devices, recent attention has been turned toward the E-field manipulation of micromagnetic elements, such as magnetic domains [18][19][20][21]. The reversible electric-field-driven magnetic domain-wall motion [22,23], and E-field control of the domain-wall mobility [24,25], have been demonstrated in different multiferroic heterostructures with simple magnetic domain structures.…”
