Nanostructure‐enhanced magnetoelectric/magnetostrictive properties and reduced losses in self‐assembled epitaxial CuFe2O4–BiFeO3 layers on Pb(Mg1/3Nb2/3)O3–33at%PbTiO3 crystals
Abstract
Self‐assembled two‐phase heterostructures of BiFeO3 and CuFe2O4 (BFO–CuFO) were deposited on (100)‐oriented SrRuO3‐buffered Pb(Mg1/3Nb2/3) O3–33at%PbTiO3 (PMN–PT) by using switching pulsed laser deposition (SPLD), and compared to single layers of CuFO on the same single crystal substrate. The CuFO phase of the self‐assembled layers had notably slimmer M‐H loops than for previously reported vertically integrated CoFe2O4 nanopillar ones, but wider ones than for CuFO/PMN–PT heterostructures. Notable changes in the magnetization of the CuFO nanopillars were found with applied DC electric field (EDC), where Mr/Ms exhibited typical butterfly‐shaped hysteresis with EDC. This was in distinct difference to CuFO/PMN–PT heterostructures which did not exhibit magnetoelectric coupling. The findings demonstrate a trade‐off between magnetoelectric/magnetostrictive properties and loss that can be controlled by nanostructure features.
