Magnetoelectric coupling tailored by the orientation of the nanocrystals in only one component in percolative multiferroic composites.

ABSTRACT: Novel 1-3 type multiferroic composite thin films were prepared via a simple 0-3 composite fabrication process. The orientation of the Ni_0.5Zn_0.5Fe₂O₄ (NZFO) nanocrystals in the BaTiO₃-Ni_0.5Zn_0.5Fe₂O₄ (BTO-NZFO) composite thin films was controlled by magnetron sputtering, and the controlling effect of such orientation on magnetoelectric coupling was investigated in detail. The NZFO lattice in the BTO-NZFO composite thin films grew with (100) orientation under the induction of the (111) plane of Si. The transfer of substrate stress between the closely contacted grains also contributes to the orientation of the NZFO nanocrystals. The 0.6BTO-0.4(100)NZFO multiferroic composite thin film ex
