摘要：
In this work, we have studied the microscopic, ferroelectric, magnetic and microstructural characteristics of cobalt ferrite/barium titanate core-shell magnetoelectric nanocomposites. Magnetoelectric nanocomposites with 22 nm mean particle size were successfully obtained and observed by High Resolution Transmission Electron Microscopy and Scanning Transmission Electron Microscopy. Ferroelectric and magnetic properties were studied and confirmed by Scanning Probe Microscopy. Ferroelectric nanoregions were observed at the nanocomposites shell and magnetic nanoregions were highlighted in the nanocomposites core. Thus, magnetoelectric nanocomposites suitable for use in multifunctional biological/biomedical/bioengineering applications, as magnetic field nanosensors and other multifunctional applications were obtained.
