Abstract

Multiferroic heterostructures consisting of Co/Pd multilayers on Pb(Mg1/3Nb2/3)O3-PbTiO3(011) substrates are experimentally investigated. The converse magnetoelectric (CME) effect is characterized by anomalous Hall effect measurements with application of an electric field (E). The remanent magnetization state for the [Co(0.8 nm)/Pd(2 nm)] multilayer is significantly modulated by the application of E. The room-temperature CME coupling coefficient (αE) is estimated to be 1.0–1.1 × 10−6 s/m, which is the largest among those of multiferroic heterostructures with perpendicular magnetic anisotropy.
