Self‐assembled two‐phase heterostructures of BiFeO 3 and CuFe 2 O 4 (BFO–CuFO) were deposited on (100)‐oriented SrRuO 3 ‐buffered Pb(Mg 1/3 Nb 2/3 ) O 3 –33at%PbTiO 3 (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 CoFe 2 O 4 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 ( E DC ), where M r / M s exhibited typical butterfly‐shaped hysteresis with E DC . 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.
