Abstract
Binary and ternary composites based on soft magnetic spinels CoFe2O4 (or CFO) and Ni0.4Cu0.2Zn0.4Fe2O4 (or NCZFO) were produced. Binary CFO/NCZFO ceramic composite was consist of two magnetic phases with 1:1 ratio. Ternary CFO:FEP, NCZFO:FEP and [CFO/NCZFO]:FEP composites were produced by the thermal pressing of the initial ceramic powders (20 wt%) and fluorinated ethylene propylene – FEP (80 wt%). XRD, SEM and VSM investigation were carried out. The impact of the chemical composition and phase ratio of the composites on crystal structure, microstructure and magnetic properties were established. Magnetic measurements were performed at 300 and 10 K in the fields up to 70 kOe. It was demonstrated the synergetic effect for ceramic composite with the violation of the principle of additivity in two-phase ceramic composites.
