| Sammanfattning: | Заглавие с экрана Herein, the magnetic properties and structure of magnetic and magnetoelectric core-shell nanoparticles (NPs) have been studied. These NPs based on biocompatible MnFe2O4 (MFO) and ferroelectric Ba0.85Ca0.15Zr0.1Ti0.9O3 (BCZT) were fabricated using new in situ microwave hydrothermal synthesis. The surface potential and magnetic properties of samples were studied by means of scanning probe microscopy. The surface potential of magnetic and magnetoelectric NPs was -4.6 ± 5.8 mV and -7.5 ± 3.1 mV, respectively. The magnetic properties of MFO NPs decreased after the formation of BCZT shell, since the average value of magnetic force microscopy phase reduced from -0.3 ± 0.1° to -0.2 ± 0.3°. These values indicate the magnetic behaviour of NPs corresponding to soft magnetic materials Текстовый файл |
