Abstract

Multilayer (14 layers, 115–122 nm thick each) BiFeO₃/CoFe₂O₄/substrate (BFO/CFO) and CoFe₂O₄/BiFeO₃/substrate (CFO/BFO) nanocomposites were obtained by the method of sol-gel synthesis. It is shown that all samples of the obtained nanocomposites have multiferroic properties at room temperature. At the same time, there is a clearly demonstrated effect of the layering order on the values of remnant polarization and magnetization of these samples. This influence originates from the much smaller size of the crystallites in the BiFeO₃ layers for the samples deposited in order (BFO/CFO) at various annealing temperatures (700, 725, and 750 °C).
